Description

Technical Field

[0001] The utility model relates to the field of wire threading, in particular to a wire threading device for fire fighting construction. Background Art

[0002] Existing patent: A wire threading device for fire protection construction (CN217334858U), which proposes that in the process of fire protection construction, the cable is immersed in the lubricating oil inside the box body so that the cable surface is coated with lubricating oil, thereby reducing the friction of the cable during subsequent threading, thereby avoiding damage to the cable due to pulling during the laying process, and improving the safety of cable laying; however, the box body filled with lubricating oil has a certain volume, and in order to prevent external dust and other impurities from entering the lubricating oil, the entire box body is sealed, leaving only a channel for the cable to pass through. When manually passing the cable end through the box body, it is impossible to ensure that the cable can be stably passed through the box body so that it can be lubricated normally, and when the lubricating oil is applied by immersion, more lubricating oil will often adhere to its surface, and too much lubricating oil will be taken away, which will cause excessive consumption of lubricating oil. Utility Model Content

[0003] In order to overcome the disadvantage that the box body containing lubricating oil has a certain volume and it is impossible to ensure that the cable end can be stably passed through the box body when manually passing the cable end through the box body, the utility model provides a threading device for fire protection construction.

[0004] The technical solution of the utility model is: a wire threading device for fire protection construction, comprising a shell, a round tube, a wire inlet and a wire outlet; the shell is connected with the round tube; the left side of the shell is provided with a wire inlet; the right side of the shell is provided with a wire outlet; the shell is provided with an observation window for observing the use of lubricating fluid; it also includes a sleeve, an electric push rod and an arc-shaped pressing block; a sleeve is provided between the wire inlet and the wire outlet, and the sleeve is set to a flexible material; a plurality of strip grooves are opened on the sleeve; the upper side of the shell is fixedly connected to the electric push rod; the telescopic part of the electric push rod is fixedly connected to the arc-shaped pressing block, and the arc-shaped pressing block is located inside the shell.

[0005] More preferably, it further comprises a convex ball; a plurality of convex balls are arranged on the inner wall of the sleeve.

[0006] More preferably, it further comprises a guide ring and bristles; the guide ring is fixedly connected to the line inlet of the shell; and a plurality of bristles are fixedly connected to the guide ring.

[0007] More preferably, it further includes a second guide ring and a scraper; the second guide ring is fixedly connected to the wire outlet of the shell, and the second guide ring is fixedly connected to the sleeve; a plurality of scrapers are fixedly connected to the upper side and the lower side of the second guide ring.

[0008] More preferably, the upper scraper is located on the left side of the lower scraper.

[0009] More preferably, it further comprises convex rods; and each scraper is fixedly connected with a plurality of convex rods.

[0011] Through the guidance and limitation of the sleeve, the cable can be passed through the shell stably by hand, and the sleeve is pressed downward by the arc-shaped pressing block, so that the sleeve bends downward and deforms, so that the cable in the sleeve can move downward and be immersed in the lubricating oil below. The lubricating oil can contact the cable through the strip groove. Subsequently, the cable only needs to be continuously passed through the shell to complete the cable immersion operation.

[0012] By arranging the convex ball on the sleeve, when the sleeve is deformed, the convex ball contacts the cable, so that there is always a gap between the cable and the sleeve, thereby avoiding the situation where some areas cannot be soaked in lubricating oil.

[0013] Excess lubricating oil adhering to the cable surface is scraped off by a scraper, and the scraped lubricating oil can flow back into the shell along the guide ring 2, so as to avoid excessive lubricating oil adhering to the cable surface and directly passing through, which will cause excessive consumption of lubricating oil and increase economic losses.

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0021] Embodiment: A wire threading device for fire fighting construction, such as Figure 1-5 As shown, it includes a housing 1, a round tube 2, a line inlet 3 and a line outlet 4; the housing 1 is connected to the round tube 2; the line inlet 3 is arranged on the left side of the housing 1; the line outlet 4 is arranged on the right side of the housing 1; the housing 1 is provided with an observation window 1a;

[0022] It also includes a sleeve 5, an electric push rod 6 and an arc-shaped pressing block 7; a sleeve 5 is arranged between the wire inlet 3 and the wire outlet 4, and the sleeve 5 is set to a flexible material; a plurality of strip grooves 5a are opened on the sleeve 5; an electric push rod 6 is fixedly connected to the upper side of the shell 1; an arc-shaped pressing block 7 is fixedly connected to the telescopic part of the electric push rod 6, and the arc-shaped pressing block 7 is located inside the shell 1.

[0023] It also includes a convex ball 8; a plurality of convex balls 8 are arranged on the inner wall of the sleeve 5.

[0024] It also includes a guide ring 101 and bristles 102; the guide ring 101 is fixedly connected to the line inlet 3 of the shell 1; and a plurality of bristles 102 are fixedly connected to the guide ring 101.

[0025] It also includes a second guide ring 111 and a scraper 113; the second guide ring 111 is fixedly connected to the outlet 4 of the housing 1, and the second guide ring 111 is fixedly connected to the sleeve 5; two scrapers 113 are fixedly connected to the upper and lower sides of the second guide ring 111.

[0026] The upper scraper 113 is located on the left side of the lower scraper 113 , and when scraping the lubricating oil on the surface of the cable, it can ensure that the excess lubricating oil on the surface is scraped off.

[0027] It also includes protruding rods 112 ; each scraper 113 is fixedly connected with a plurality of protruding rods 112 .

[0028] The housing 1 further includes a bracket 121 ; the bracket 121 is fixedly connected to the housing 1 .

[0029] The working steps of the above embodiment are as follows: in the specific work, the required lubricating oil is first added into the housing 1 through the round tube 2, and the electric push rod 6 is powered on; then when lubricating the cable, the entire device is first fixed by the bracket 121, and then the cable end is manually inserted into the inlet 3 through the guide ring 101, and then the cable is manually pushed to the right. Under the guidance and limit of the sleeve 5, the cable end can be stably moved to the outlet 4 on the right, and pass through the outlet 4 through the guidance of the guide ring 2 111, as shown in FIG. Figure 1As shown, in this way, through the guide limit of the sleeve 5, the cable can be stably passed through the housing 1 manually; then the electric push rod 6 is controlled to drive the arc-shaped pressing block 7 to move downward, and the arc-shaped pressing block 7 moves downward to press the sleeve 5, so that the sleeve 5 bends and deforms downward, so that the cable in the sleeve 5 can move downward and be immersed in the lubricating oil below. The lubricating oil can contact the cable through the strip groove 5a. Subsequently, it is only necessary to continuously pass the cable through the housing 1 to complete the cable immersion operation;

[0030] However, after the sleeve 5 is bent and deformed, the lower side of the sleeve 5 is easily deformed and fits with the cable, resulting in that when the cable is soaked in lubricating oil, the fitting part cannot contact with the lubricating oil. Therefore, by providing the convex ball 8 on the sleeve 5, when the sleeve 5 is deformed, the convex ball 8 contacts with the cable, so that there is always a gap between the cable and the sleeve 5, avoiding the situation that some areas cannot be soaked in lubricating oil.

[0031] Furthermore, when the cable enters the cable inlet 3 through the guide ring 101, the cable can be brushed and cleaned by the bristles 102 on the guide ring 101 to brush off the dust attached to the cable surface, thereby preventing the dust attached to the cable surface from directly contacting the lubricating oil, causing the lubricating oil to be contaminated and reducing the lubricating effect of the lubricating oil;

[0032] At the same time, after the cable is soaked in lubricating oil, in the process of passing through the guide ring 111 to pass through the outlet 4, the cable first passes through the scraper 113, and then the cable passes through the scraper 113 to pass through the outlet 4; and in the process of the cable passing through the scraper 113, the excess lubricating oil attached to the surface of the cable can be scraped off by the scraper 113, and the scraped lubricating oil can flow back into the shell 1 along the guide ring 111, so that too much lubricating oil is avoided from adhering to the surface of the cable. If the cable passes through directly, it will cause excessive consumption of lubricating oil and increase economic damage; and the scraper 113 is provided with a convex rod 112, so that the scraper 113 will not fit tightly with the cable, and there is a certain gap between them, so that when the scraper 113 scrapes the surface of the cable, the scraper 113 will not scrape off all the lubricating oil on the surface of the cable. After scraping off the lubricating oil, a certain amount of lubricating oil still remains on the surface of the cable, ensuring the lubrication effect of the subsequent cable.

[0033] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
