Description

Technical Field

[0001] This utility model relates to the field of hydraulic support hose installation technology in coal mines, specifically, to a protective and storage device for the entry of the roadway hose into the hydraulic support. Background Technology

[0002] When hydraulic supports are in operation, they need to use emulsion as a medium to transmit power. The emulsion in the coal mine is stored in an emulsion tank. After being pressurized by a pump station, it is transported to the hydraulic supports and other equipment (transfer conveyors, scraper conveyors) through rubber hoses arranged along the roadway wall.

[0003] Currently, the following are the main problems encountered when the hose enters the hydraulic support in the roadway:

[0004] (1) The hoses are scattered and the arrangement is not aesthetically pleasing;

[0005] (2) The hose lacks protection and is easily worn during the working face advance;

[0006] (3) The hose is not properly secured, and it is easy for it to swing and injure people when pressure is applied;

[0007] (4) The hose crosses the pedestrian passage of the hydraulic support, which may affect the passage of staff.

[0008] Chinese utility model patent CN2022205421045 discloses a hose anti-detachment device, including a base, a protective top plate, a connecting sleeve, a connecting bolt, and clamps for fastening the hose. The protective top plate is installed above the base via the connecting sleeve. The connecting bolt passes through the protective top plate, the connecting sleeve, and the base sequentially from top to bottom, with its lower end protruding from the base. A clamp is installed on each side of the base opposite to the connecting sleeve. This hose anti-detachment device improves the installation stability of the hose by clamping it, effectively preventing the hose joint from detaching from the hydraulic support joint. However, the section of the hose entering the hydraulic support from the chute lacks protection, failing to solve the aforementioned problem. Summary of the Invention

[0009] The purpose of this invention is to address the shortcomings of existing technologies by providing a protective and storage device for the hose entering the hydraulic support in the trench. This invention is aesthetically pleasing, constrains and protects the hose, prevents hose wear, avoids hose swinging that could injure people, and avoids obstructing the passage of workers.

[0010] To achieve the above objectives, the technical solution adopted by this utility model is: a protective and storage device for a grooving hose entering a hydraulic support, comprising a chain hose clamp, the two ends of which are respectively connected to the scraper conveyor and the top beam of the hydraulic support. The hose entering the hydraulic support is led out from the scraper conveyor and passes through the chain hose clamp and slides inside the chain hose. After passing through the chain hose clamp, the hose is connected to the main multi-pass block of the hydraulic support.

[0011] Based on the above, it also includes an entry position adjustment component, which is installed on the top beam of the hydraulic support. The two ends of the chain hose clamp are respectively connected to the scraper conveyor and the entry position adjustment component. The entry position adjustment component is used to adjust the position of the chain hose clamp on the top beam of the hydraulic support to adjust the degree of bending of the hose.

[0012] Based on the above, the entry position adjustment assembly includes a base plate, a connecting plate, and a support plate. The base plate is mounted on the top beam of the hydraulic support. A slide rail is provided on the base plate along the front-to-back direction. The connecting plate and the support plate are slidably disposed on the slide rail at intervals and can be fixedly connected to the base plate through a first connector. The chain hose clamp passes through the support plate and the base plate. The support plate is used to support the chain hose clamp and the hose. The two ends of the chain hose clamp are respectively hinged to the scraper and the connecting plate.

[0013] Based on the above, the entry position adjustment assembly further includes an adapter plate, which is slidably mounted on the slide rail and can be fixedly connected to the base plate through a second connector. A pipe connector is provided on a section of the hose after it passes through the chain hose clamp, and the pipe connector is fixedly mounted on the adapter plate.

[0014] Based on the above, the connecting plate and the support plate are integrally formed and fixedly connected as a single component.

[0015] This utility model has substantial features and advancements compared to existing technologies. Specifically, this utility model centrally arranges the hoses entering the hydraulic support within a chain hose clamp, resulting in an aesthetically pleasing arrangement that restrains and protects the hoses, preventing wear. The two ends of the chain hose clamp are respectively connected to the scraper conveyor and the top beam of the hydraulic support, thereby fixing the hoses in place and preventing them from swinging and injuring people. Furthermore, when the hoses enter the hydraulic support, they are directly fixed to the top beam of the hydraulic support by the chain hose clamp, allowing the hoses to enter the hydraulic support before the pedestrian walkway, thus avoiding obstruction of staff passage.

[0016] Furthermore, based on the bending condition of the hose on site, the position of the chain hose clamped on the top beam of the hydraulic support can be flexibly adjusted by setting an entry position adjustment component, so that the hose reaches the optimal state and avoids the hose being too bent or too tight.

[0024] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0025] like Figures 1-5 As shown, a protective and storage device for a hose entering a hydraulic support in a trench includes a chain hose clamp 1. Both ends of the chain hose clamp 1 are connected to a scraper conveyor 2 and a top beam 3 of the hydraulic support, respectively. The hose 5 entering the hydraulic support 4 is led out from the scraper conveyor 2 and passes through the chain hose clamp 1. After exiting the chain hose clamp 1, the hose 5 connects to the main multi-pass block 6 of the hydraulic support 4. This arrangement allows the hoses 5 entering the hydraulic support 4 to be centrally arranged in the chain hose clamp 1, resulting in an aesthetically pleasing arrangement. It also restrains and protects the hoses 5, preventing wear and tear and fixing them in place to avoid injury from swinging.

[0026] The hydraulic support top beam 3 is equipped with an entry position adjustment component 7. The two ends of the chain hose clamp 1 are respectively connected to the scraper conveyor 2 and the entry position adjustment component 7. The entry position adjustment component 7 is used to adjust the position of the chain hose clamp 1 on the hydraulic support top beam 3 to adjust the degree of bending of the hose 5.

[0027] The entry position adjustment assembly 7 includes a base plate 8, a connecting plate 9, and a support plate 10. The base plate 8 is bolted to the hydraulic support top beam 3. Multiple bolt mounting holes are reserved on the base plate 8 or the hydraulic support top beam 3. Thus, the front and rear positions of the base plate 8 on the hydraulic support top beam 3 can be adjusted according to the actual situation downhole, thereby adjusting the position of the entire entry position adjustment assembly 7. A slide rail 11 is provided on the base plate 8 along the front and rear direction. The connecting plate 9 and the support plate 10 are slidably disposed on the slide rail 11 at intervals and can be fixedly connected to the base plate 8 through a first connecting member. The chain hose clamp 1 passes between the support plate 10 and the base plate 8. The support plate 10 is used to support the chain hose clamp 1 and the hose 5. The two ends of the chain hose clamp 1 are respectively hinged to the scraper conveyor 2 and the connecting plate 9. Based on the bending condition of the hose 5 on site, the position of the chain hose clamp 1 on the hydraulic support top beam 3 can be flexibly adjusted by adjusting the position of the base plate 8 and the connecting plate 9, so that the hose 5 can reach the optimal state and avoid the hose 5 being too bent or too tight.

[0028] Furthermore, a transition plate 12 is also slidably mounted on the slide rail 11, and the transition plate 12 is fixedly connected to the base plate 8 through a second connector.

[0029] Specifically, the slide rail 11 has several first pin holes 13 spaced apart on both sides. The first and second connecting parts are both pins 14. The connecting plate 9, the support plate 10, and the adapter plate 12 have ear plates with second pin holes 15 on both sides. The connecting plate 9, the support plate 10, and the adapter plate 12 can be freely combined and installed on the base plate 8 and slide on the slide rail 11. After sliding to a suitable position, the connecting plate 9, the support plate 10, and the adapter plate 12 are fixed on the base plate 8 by the pins 14 passing through the corresponding first pin holes 13 and second pin holes 15.

[0030] In this embodiment, the adapter plate 12, the connecting plate 9, and the support plate 10 are arranged from front to back on the slide rail 11. One end of the chain hose clamp 1 is hinged to the scraper machine 2, and the other end passes from back to front between the support plate 10 and the base plate 8 and is then hinged to the connecting plate 9. The hose 5 led out from the scraper machine 2 passes through the chain hose clamp 1. A pipe connector 16 is provided on the section of the hose 5 after it passes through the chain hose clamp 1. The pipe connector 16 is fixedly installed on the adapter plate 12, thereby fixing the hose 5 to the top beam 3 of the hydraulic support, so that the hose 5 enters the hydraulic support 4 before the pedestrian passage 22, avoiding affecting the passage of workers.

[0031] In this embodiment, the chain-type hose clamp 1 is mainly composed of several hose clamps. Each hose clamp is hinged end to end in a chain-like structure. The hose clamps at both ends are respectively hinged to the scraper machine 2 and the connecting plate 9. The hose 5 is inserted through each hose clamp.

[0032] The pipe clamp mainly consists of two clamping plates 17, with tensioning bolts 18 connecting both sides of the two clamping plates 17. The hose 5 passes between the two clamping plates 17, and a partition plate 19 connects the two clamping plates 17. Adjacent pipe clamps are hinged through corresponding partition plates 19. The clamping plates 17 protect the hose 5 and prevent it from wearing out. The tensioning bolts 18 provide tension and prevent the hose 5 from coming loose. The partition plates 19 separate different hoses 5, preventing them from tangling, making the hoses neater, and increasing the overall structural strength and stability of the pipe clamp.

[0033] One end of the partition 19 is provided with an outwardly protruding hinge plate 20, and the other end of the partition 19 is provided with an outwardly protruding hinge support 21. Two adjacent pipe clamps are hinged together by the corresponding hinge plate 20 and hinge support 21.

[0034] In practical use, the cable 23 entering the hydraulic support 4 can also be arranged together with the hose 5 in the chain hose clamp 1, which also avoids the cable 23 from being scattered, protects the cable 23, and prevents the cable 23 from being worn.

[0035] like Figure 6 As shown, in other embodiments, only the connecting plate 9 and the support plate 10 are installed on the slide 11, with the support plate 10 in front and the connecting plate 9 behind. One end of the chain hose clamp 1 is hinged to the scraper machine 2, and the other end passes from front to back between the support plate 10 and the base plate 8 and is then hinged to the connecting plate 9.

[0036] In other embodiments, the base plate 8 can be omitted, and the connecting plate 9 and the support plate 10 can be directly fixed to the hydraulic support top beam 3 with bolts.

[0037] In other embodiments, the connecting plate 9 and the support plate 10 can be combined into one component, reducing the number of components and simplifying the structure. Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications should be covered within the scope of the technical solution claimed by this utility model.
