Description

Technical Field

[0001] This utility model relates to a spraying device, and in particular to a spraying device for the production of construction hoists, which is applied in the field of construction hoist manufacturing. Background Technology

[0002] Construction elevators are often called construction hoists, but the definition of a construction hoist is broader, including construction platforms. A typical construction elevator consists of several parts, including a car, drive mechanism, standard sections, wall attachments, chassis, railings, and electrical system. It is a commonly used construction machine for carrying people and goods. Due to its unique box structure, it is both comfortable and safe to ride. Construction elevators are usually used in conjunction with tower cranes on construction sites. During the production process of construction hoists, spraying equipment is used to coat the surfaces of the components.

[0003] The specification of Chinese Patent Publication No. CN208991045U discloses a surface spraying device for elevator production. This utility model increases the length of the oil outlet pipe in the connection between the oil pump and the first and second nozzles, which can expand the spraying range of the spraying device. At the same time, a rotating drum is installed on the base to store the oil outlet pipe, so as not to make the storage of the oil outlet pipe messy. The rotating drum makes it convenient to use the oil outlet pipe.

[0004] However, the above-mentioned patents may encounter the following problems in actual application: When spraying the surface of the elevator, the high-pressure nozzle is usually directly connected to the pipe thread. After a long period of use, the high-pressure nozzle may become loose. If the high-pressure nozzle is used again, it may be pushed out and fall off due to the strong pressure, which may cause injury to personnel. Utility Model Content

[0005] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is that when spraying the surface of the elevator with a high-pressure nozzle, the nozzle may be pushed out and fall off due to loose threads, which reduces the safety of the spraying device during use.

[0006] To address the aforementioned problems, this utility model provides a spraying device for construction hoist production, comprising a trolley, with a container and a liquid pump fixedly connected to the upper end of the trolley. The container is located to the left of the liquid pump, and an inlet pipe is fixedly connected between the container and the liquid pump. An outlet pipe is fixedly connected to the outlet of the liquid pump, and a spraying assembly is fixedly connected to the end of the outlet pipe away from the liquid pump. The spraying assembly includes a mounting pipe fixedly connected to the end of the outlet pipe, a nozzle being threadedly connected to the inner cavity of the mounting pipe, and a mounting plate being fixedly sleeved on the outer surface of the mounting pipe. Two rods are fixedly connected to one end of the mounting plate near the nozzle. A positioning plate and a limiting plate are fitted on the outer surface of the nozzle. The positioning plate is fixedly fitted on the outer surface of the nozzle, and the limiting plate is movably fitted on the outer surface of the nozzle. The positioning plate is located at the end of the limiting plate near the rod. Two limiting holes corresponding to the two rods are chiseled on the surface of the limiting plate. The end of the rod away from the mounting plate moves through the adjacent limiting hole. A receiving groove is chiseled on the surface of the rod. Two stop rods are rotatably connected in the receiving groove. A spring is fixedly connected between the two stop rods.

[0007] In the above-mentioned spraying device for construction hoist production, compared with the existing spraying device, this utility model reinforces the nozzle by setting up a spraying component during the installation of the nozzle, making it less likely for the nozzle to fall off during use, thereby effectively improving the safety of the spraying device during use.

[0008] As a further improvement to this application, the outlet pipe is a flexible tube and the installation pipe is a rigid tube.

[0009] As a further improvement to this application, the two stop levers are arranged in an inverted V-shape, the end of the stop lever near the limiting plate is rounded, and the stop lever is in contact with the limiting plate, with the spring piece being arc-shaped.

[0010] As a further improvement of this application, the height of the receiving groove is greater than the length of the stop bar, the limiting plate and the positioning plate are fitted together, and the lower end of the insertion rod is rounded.

[0011] As another improvement of this application, a protective cover is fixedly fitted on the outer surface of the mounting plate, and the cross-section of the protective cover is trapezoidal.

[0012] As a further improvement to this application, a handle is fixedly connected to the outer surface of the protective cover, and an L-shaped hanging rod is fixedly connected to the outer surface of the container.

[0013] In summary, when installing the spray head, first screw the spray head into the installation tube, then push the limiting plate upwards so that the limiting hole on the limiting plate is below the insert rod. Then insert the insert rod into the limiting hole, and the two stop rods rotate inwards under force, causing the spring to deform inwards until the limiting plate and the positioning plate are in contact. The pressure on the stop rods disappears and they reset, and the rounded corners of the stop rods contact the limiting plate, thus providing secondary fixation for the spray head. This makes it less likely for the spray head to fall off during use, thereby effectively improving the safety of the spraying device. Attached Figure Description

[0023] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0024] First implementation method:

[0025] Figure 1 and Figure 2The diagram shows a spraying device for the production of a construction hoist, including a trolley 1. A container 2 and a liquid pump 3 are fixedly connected to the upper end of the trolley 1. Those skilled in the art can select a suitable model of liquid pump 3 according to actual needs, such as XBD7.6 / 5W. The container 2 is located to the left of the liquid pump 3, and an inlet pipe 4 is fixedly connected between the container 2 and the liquid pump 3. An outlet pipe 5 is fixedly connected to the outlet of the liquid pump 3. The outlet pipe 5 is a flexible hose, which facilitates the worker to adjust the position of the spray nozzle 7 to facilitate spraying the hoist. A spraying component is fixedly connected to the end of the outlet pipe 5 away from the liquid pump 3.

[0026] Figure 3 , Figure 4 , Figure 5 and Figure 6 The spraying assembly includes a mounting tube 6 fixedly connected to the end of the liquid outlet pipe 5. The mounting tube 6 is a rigid tube to facilitate the installation of the spray head 7. The inner cavity of the mounting tube 6 is threaded with the spray head 7. A mounting plate 8 is fixedly sleeved on the outer surface of the mounting tube 6. Two insertion rods 9 are fixedly connected to one end of the mounting plate 8 near the spray head 7. The lower ends of the insertion rods 9 are rounded to facilitate insertion of the insertion rods 9 into the limiting hole 12. A positioning plate 10 and a limiting plate 11 are sleeved on the outer surface of the spray head 7. The positioning plate 10 is fixed. A limiting plate 11 is fitted onto the outer surface of the nozzle 7, and is movably fitted onto the outer surface of the nozzle 7. The limiting plate 11 is in contact with the positioning plate 10. The positioning plate 10 can limit one end of the limiting plate 11, while the stop bar 14 can limit the other end of the limiting plate 11, thus making it difficult for the limiting plate 11 to move. The positioning plate 10 is located at the end of the limiting plate 11 near the insertion rod 9. The surface of the limiting plate 11 has two limiting holes 12 respectively corresponding to the two insertion rods 9. One end of the rod 9, movably passing through the adjacent limiting hole 12, has a receiving groove 13 carved into its surface. Two stop rods 14 are rotatably connected within the receiving groove 13, and a spring piece 15 is fixedly connected between the two stop rods 14. The two stop rods 14 are arranged in an inverted V-shape. The end of each stop rod 14 near the limiting plate 11 is rounded, and the stop rod 14 contacts the limiting plate 11. The stop rod 14 can abut against the limiting plate 11, making it difficult for the limiting plate 11 to move. The nozzle 7 is fixed in a limiting position. The spring 15 is arc-shaped, and the height of the receiving groove 13 is greater than the length of the stop bar 14, which facilitates the rotation of the stop bar 14. A protective cover 18 is fixedly fitted on the outer surface of the mounting plate 8. The protective cover 18 has a trapezoidal cross section and can protect the internal parts. When replacing the nozzle 7, the stop bar 14 can be pressed inward to deform the spring 15. Then, the limiting plate 11 can be pulled to disengage the insertion rod 9 from the limiting hole 12, and then the nozzle 7 can be unscrewed.

[0027] When installing the nozzle 7, first screw the nozzle 7 into the mounting tube 6, then push the limiting plate 11 upward so that the limiting hole 12 on the limiting plate 11 is below the insertion rod 9. Then insert the insertion rod 9 into the limiting hole 12. The two stop rods 14 are forced to rotate inward, and the spring piece 15 deforms inward until the limiting plate 11 and the positioning plate 10 are in contact. The pressure on the stop rods 14 disappears and they reset. The rounded corners of the stop rods 14 contact the limiting plate 11, thereby fixing the nozzle 7 a second time. This makes it less likely for the nozzle 7 to fall off during use, thus effectively improving the safety of the spraying device during use.

[0028] Second implementation method:

[0029] This embodiment adds a handle 16 and a hanging rod 17 to the first embodiment, while the rest remains the same as the first embodiment.

[0030] Figure 7 As shown: a handle 16 is fixedly connected to the outer surface of the protective cover 18, and an L-shaped hanging rod 17 is fixedly connected to the outer surface of the container 2.

[0031] When spraying the elevator, the operator can hold the handle 16 to adjust the position of the nozzle 7. When not in use, the handle 16 can be hung on the hanging rod 17 to suspend the spraying components for easy access later.

[0032] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
