Description

Technical Field

[0001] This utility model relates to the field of coal mine roadway technology, specifically to a liftable and telescopic personnel platform. Background Technology

[0002] Currently, the working platform of the tunneling and anchoring machine adopts a relatively single height and a relatively fixed operating plane. However, the working plane and working conditions of the tunneling and anchoring machine change frequently, which leads to many limitations on the machine during operation.

[0003] Therefore, the existing technology needs further improvement. Utility Model Content

[0004] To address the shortcomings of existing technologies, a height-adjustable and telescopic personnel platform is proposed. This solves the problem that existing tunneling and anchoring integrated machine work platforms use a relatively single height and a relatively fixed operating plane, while the working plane and working conditions of the tunneling and anchoring integrated machine change frequently, which leads to many limitations on the whole machine during operation.

[0005] To achieve the above objectives, the present invention proposes the following technologies:

[0006] A liftable and retractable personnel platform includes a support platform with an adjustable width. A lifting assembly is fixedly connected to the bottom of the support platform. The lifting assembly supports the support platform and raises or lowers the support platform by telescoping to adapt to different roadways.

[0007] Furthermore, the lifting assembly includes a primary sleeve and a secondary sleeve. The primary sleeve is fixedly connected to the support platform via a connecting seat, and the primary sleeve is inserted into the secondary sleeve and slidably connected to it.

[0008] Furthermore, the secondary sleeve is equipped with a drive structure inside. The output end of the drive structure is connected to the connecting seat, and drives the connecting seat to move the primary sleeve and the secondary sleeve relative to each other to realize the lifting and lowering of the support platform.

[0009] Furthermore, a limiting cap is provided at the top of the secondary sleeve, the inner diameter of which is smaller than the inner diameter of the secondary sleeve. Correspondingly, a first-level limiting step is provided on the outside of the primary sleeve, the first-level limiting step abutting against the limiting cap to restrict the extension of the primary sleeve.

[0010] Furthermore, the lifting assembly also includes a three-stage sleeve, the second-stage sleeve is inserted into the third-stage sleeve and slidably connected to the third-stage sleeve, the inner wall of the third-stage sleeve is provided with a three-stage limiting step, and the outer side of the corresponding second-stage sleeve is provided with a second-stage limiting step that matches the three-stage limiting step.

[0011] Furthermore, the support platform includes a lower platform fixedly connected to the lifting assembly, and an upper platform slidably connected to the lower platform. The upper platform slides relative to the lower platform to change the width of the support platform to achieve telescopic extension.

[0012] Furthermore, a slide is provided above the lower platform, and a guide rail is slidably connected inside the slide. The guide rail is fixedly connected to the lower part of the upper platform, and the guide rail slides along the extension direction of the slide to drive the upper platform and the lower platform to slide relative to each other to adjust the width of the support platform.

[0013] Furthermore, the slide includes a first slide and a second slide fixed at both ends of the lower platform. A first guide rail and a second guide rail are respectively installed in the first slide and the second slide. A third slide is provided between the first slide and the second slide, and a third guide rail is installed in the third slide.

[0014] Furthermore, a first mounting seat is provided on each side of the third slide rail, and a second mounting seat is provided on each side of the third guide rail. The first and second mounting seats are respectively connected to the two ends of the telescopic power structure.

[0015] Furthermore, the surface of the upper platform is detachably connected to a station plate assembly, which includes multiple station plates of equal height. The multiple station plates are spliced ​​together, and the shape of the station plates matches the shape of the upper platform.

[0016] Compared with the prior art, the comprehensive effects brought about by this utility model include:

[0017] This application, by setting up a lifting and telescopic support platform, allows the height of the support platform to be adjusted according to different roadway heights, thereby adjusting the overall height of the tunneling and anchoring machine.

[0027] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Terms such as "upper," "lower," "left," "right," and "top" indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are used only for the convenience of describing the present invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0029] like Figures 1 to 8 As shown, a liftable and retractable personnel platform includes a support platform with an adjustable width. A lifting assembly is fixedly connected to the bottom of the support platform. The lifting assembly supports the support platform and raises or lowers the support platform by telescoping to adapt to different roadways.

[0030] By adopting a lifting and telescopic work platform, the height of the support platform can be adjusted according to different roadway heights, thereby adjusting the overall height of the tunneling and anchoring machine. Similarly, the width of the support platform can be adjusted according to different roadway widths, thereby adjusting the overall width of the machine. This allows the tunneling and anchoring machine to adapt to more working conditions and minimizes the overall height and width during equipment transportation, facilitating transport.

[0031] This application has a simple structure and can control the power mechanism to drive the support platform and lifting components to perform lifting and telescopic operations via remote control or operating handle. It is easy to operate and highly adaptable.

[0032] In the height-adjustable telescopic platform of this embodiment, the lifting component includes a primary sleeve 1 and a secondary sleeve 2. The primary sleeve 1 is fixedly connected to the support platform through a connecting seat 3. The primary sleeve 1 is inserted into the secondary sleeve 2 and is slidably connected to the secondary sleeve 2.

[0033] Specifically, the secondary sleeve 2 is equipped with a drive structure inside. The output end of the drive structure is connected to the connecting seat 3, and drives the connecting seat 3 to drive the primary sleeve 1 and the secondary sleeve 2 to slide relative to each other to realize the lifting and lowering of the support platform.

[0034] A power device is installed inside the secondary sleeve 2 to drive the lifting and lowering of the primary sleeve 1 and the support platform, making the most of the limited space. The primary sleeve 1 and the secondary sleeve 2 work together to guide the lifting and lowering of the support platform, ensuring smooth raising or lowering.

[0035] In the height-adjustable telescopic platform of this embodiment, the top of the secondary sleeve 2 is provided with a limit cover 4. The inner diameter of the limit cover 4 is smaller than the inner diameter of the secondary sleeve 2. Correspondingly, the outer side of the primary sleeve 1 is provided with a first-level limit step 5. The first-level limit step 5 abuts against the limit cover 4 to restrict the extension of the primary sleeve 1.

[0036] By setting a limiting cover 4 and a first-level limiting step 5, the maximum length of the first-level sleeve 1 extending out of the second-level sleeve 2 is limited, thus preventing the first-level sleeve 1 from detaching from the second-level sleeve 2.

[0037] In the height-adjustable telescopic platform of this embodiment, the lifting assembly further includes a three-stage sleeve 6, and the two-stage sleeve 2 is inserted into the three-stage sleeve 6 and slidably connected to the three-stage sleeve 6. The inner wall of the three-stage sleeve 6 is provided with a three-stage limiting step 7, and the outer side of the corresponding two-stage sleeve 2 is provided with a two-stage limiting step that matches the three-stage limiting step 7.

[0038] Specifically, in the lifting system of this application, two sets of lifting components are provided below the support platform, connecting the support platform and the whole machine from both sides to provide stable support for the support platform. Lifting is achieved through three lifting sleeves. Limiting steps are provided on the secondary sleeve 2 and the tertiary sleeve 6 to prevent the secondary sleeve 2 from detaching from the tertiary sleeve 6. The connecting seat 3 and the primary sleeve 1 are integrated as a whole and are bolted to the bottom of the support platform. The bottom of the tertiary sleeve 6 is provided with a base 21 to provide stable support for the lifting components and is bolted to the whole machine, maximizing the use of the space of the whole machine.

[0039] Preferably, the outer diameter of the limiting cover 4 is larger than the outer diameter of the third-stage sleeve 6. When the second-stage sleeve 2 retracts into the third-stage sleeve 6, the limiting cover 4 abuts against the top of the third-stage sleeve 6, limiting the minimum height of the support platform's lifting and lowering, so that the lifting system is within a safe range.

[0040] Preferably, the side walls of the secondary sleeve 2 and the tertiary sleeve 6 are provided with several limiting holes, and limiting pins can be inserted into the limiting holes. After the extension length of the primary sleeve 1 and the secondary sleeve 2 is fixed, the limiting pins are inserted into the limiting holes at the corresponding heights of the secondary sleeve 2 and the tertiary sleeve 6 to support and limit the bottom ends of the primary sleeve 1 and the secondary sleeve 2.

[0041] In this embodiment of the height-adjustable telescopic platform, the support platform includes a lower platform 8 fixedly connected to the lifting assembly, and an upper platform 9 slidably connected to the lower platform 8. The upper platform 9 slides relative to the lower platform 8 to change the width of the support platform to achieve telescopic extension.

[0042] Specifically, a telescopic power structure is set in the middle of the upper and lower platforms for power connection, which pushes the upper platform 9 to slide above the lower platform 8. By adjusting the running length of the power structure, the telescopic length of the support platform can be adjusted and limited so that the overall width after telescopic movement is within a safe range.

[0043] In this embodiment of the height-adjustable telescopic platform, a slide is provided above the lower platform 8, and a guide rail is slidably connected inside the slide. The guide rail is fixedly connected below the upper platform 9, and the guide rail slides along the extension direction of the slide to drive the upper platform 9 and the lower platform 8 to slide relative to each other to adjust the width of the support platform.

[0044] Specifically, the slide is bolted to the upper surface of the lower platform 8, and wear-resistant copper strips 20 are installed inside the slide. The upper platform 9 is connected to the slide through a guide rail. The guide rail and the lower platform 8 are an integral mechanism. The upper platform 9 slides in the slide through the guide rail to adjust the overall width of the support platform. The slide guides the sliding direction of the guide rail and limits the guide rail to prevent the upper platform 9 from being misaligned with the lower platform 8.

[0045] In the height-adjustable telescopic platform of this embodiment, the slide includes a first slide 10 and a second slide 11 fixed at both ends of the lower platform 8. A first guide rail 12 and a second guide rail 13 are respectively installed in the first slide 10 and the second slide 11. A third slide 14 is provided between the first slide 10 and the second slide 11. A third guide rail 15 is installed in the third slide 14.

[0046] By setting up three sets of slide rails and guide rails, the upper and lower platforms are evenly supported, so that the upper platform 9 is subjected to uniform force, ensuring that the upper platform 9 and the lower platform 8 slide smoothly to adjust the telescopic width.

[0047] In the height-adjustable telescopic platform of this embodiment, first mounting seats 16 are respectively provided on both sides of the third slide rail 14, and second mounting seats 17 are respectively provided on both sides of the third guide rail 15. The first mounting seats 16 and the second mounting seats 17 are respectively connected to the two ends of the telescopic power structure.

[0048] Specifically, the telescopic power mechanism is selected as a cylinder. The two ends of the cylinder are fixedly connected to the upper platform 9 and the lower platform 8 respectively. The cylinders on both sides of the third slide 14 in the middle extend or retract synchronously to push or pull the upper platform 9 to slide on the lower platform 8 to realize the telescopic movement of the support platform.

[0049] In this embodiment of the height-adjustable telescopic platform, the surface of the upper platform 9 is detachably connected to a platform assembly. The platform assembly includes multiple platform 18s of equal height, which are spliced ​​together. The shape of the platform 18 matches the shape of the upper platform 9.

[0050] The flatness of the support platform is adjusted by setting up the station plate 18. The station plate 18 has positions for installing each operating box 19 to facilitate equipment installation. The station plate 18 makes it easier for staff to stand and walk on the support platform or operate the equipment. For safety reasons, the number of steps on the support platform is reduced to avoid collisions and other problems.
