Technical Field
[0001] This utility model belongs to the technical field of mine roadway support equipment, and in particular relates to a hydraulically driven multi-stage lifting anchor trolley. Background Technology
[0002] Currently, anchor bolt trolleys cannot safely and efficiently complete high-altitude anchor cable operations, and have the following technical defects: It has poor adaptability, making it difficult to carry out operations in low-lying tunnels, while lacking a stable anchor cable operation platform in high-lying tunnels; its function is limited, only supporting anchor bolt installation, and cannot meet the high-altitude operation requirements of anchor cable construction.
[0003] While existing technologies have proposed solutions for upgrading lifting platforms, they still suffer from problems such as insufficient thrust, poor safety performance, inability to extend the corresponding lifting platform, easy contact with the ground during operation leading to deformation of the lifting platform, and lack of integrated material storage functions. Summary of the Invention
[0004] To address the problems of poor height adaptability and limited functionality of existing trolleys, this utility model provides a hydraulically driven multi-stage lifting anchor trolley. The technical solution includes a trolley boom and a multi-stage lifting system. The multi-stage lifting system is mounted on the trolley boom and includes a primary guide rail, a secondary guide rail, a hydraulic cylinder, and a suspended platform. The primary guide rail is detachably connected to the trolley boom, and its bottom is fixedly connected to the cylinder body of the hydraulic cylinder. A secondary guide rail is fixedly mounted on the sliding seat of the primary guide rail, and the slider of the secondary guide rail is fixedly connected to the upper part of the side wall of the suspended platform. The lower part of the side wall of the suspended platform is hinged to the end of the hydraulic rod of the hydraulic cylinder.
[0005] In a preferred embodiment, a limiting baffle is provided on the primary guide rail, and a limiting plate is fixedly provided on the sliding seat of the primary guide rail. The limiting baffle and the limiting plate cooperate to restrict the sliding seat from exceeding the travel along the groove of the primary guide rail.
[0006] In a preferred embodiment, the upper and lower ends of the slide groove of the secondary guide rail are respectively provided with a first limiting plate and a second limiting plate, which are used to limit the slider of the secondary guide rail from exceeding the stroke along the slide groove of the secondary guide rail.
[0007] In a preferred embodiment, the primary guide rail and the trolley boom are detachably connected by a clamp.
[0008] In a preferred embodiment, the groove length of the primary guide rail is 1.4-1.6m, and the groove length of the secondary guide rail is 0.8-1.1m.
[0009] In a preferred embodiment, the lower part of the side wall of the suspended platform is hinged to the end of the hydraulic rod of the hydraulic cylinder via a hinge seat.
[0010] As a preferred embodiment, the top of the suspended platform is equipped with an anti-smashing baffle to prevent falling rocks and other foreign objects from injuring workers.
[0011] In a preferred embodiment, the bottom of the suspended basket is provided with a storage groove, which has a U-shaped structure to facilitate workers to step on it, and can hold pallets and tools.
[0012] The beneficial effects of this utility model are: (1) Through the multi-stage telescopic cooperation of the first-level guide rail and the second-level guide rail, combined with the hydraulic cylinder drive, the height of the basket can be flexibly adjusted to meet the needs of mine roadway operations with different roof heights. Whether it is compact operation in low roadways or high-altitude anchor cable construction in high-roof roadways, it can provide a stable working platform, completely solve the problem of poor height adaptability of traditional equipment, and expand the application range of the equipment. (2) The first-level guide rail, through the cooperation of the limit baffle and the limit plate, restricts the sliding seat from exceeding the stroke; the second-level guide rail, through the first and second limit plates at the upper and lower ends of the slide, locks the movement range of the slider. The double limit structure accurately controls the extension and retraction stroke of the guide rail, avoids structural collision and deformation caused by overtravel during the lifting process, and at the same time ensures that the lifting of the basket is stable and without shaking, thus ensuring the structural stability of high-altitude operations. (3) The U-shaped storage slot at the bottom of the suspended platform can directly place construction materials such as pallets, anchor cables, and tools, so that workers do not need to go back and forth to the ground to retrieve items, which greatly shortens the operation time. The detachable primary guide rail is connected to the trolley boom through a clamp, which is convenient for equipment installation and maintenance, and can also adapt to the modification needs of different models of anchor bolt trolleys, reduce equipment replacement costs, and improve construction continuity.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0019] Example like Figure 1-4 The diagram shows a hydraulically driven multi-stage lifting anchor trolley, comprising a trolley boom 1 and a multi-stage lifting system. The multi-stage lifting system is mounted on the trolley boom 1 and includes a primary guide rail 2, a secondary guide rail 3, a hydraulic cylinder 4, and a suspended platform 5. The primary guide rail 2 is detachably connected to the trolley boom 1, and the bottom of the primary guide rail 2 is fixedly connected to the cylinder body of the hydraulic cylinder 4. The secondary guide rail 3 is fixedly mounted on the sliding seat 201 of the primary guide rail 2, and the slider 301 of the secondary guide rail 3 is fixedly connected to the upper part of the side wall of the suspended platform 5. The lower part of the side wall of the suspended platform 5 is hinged to the end of the hydraulic rod of the hydraulic cylinder 4.
[0020] Furthermore, a limiting baffle 202 is provided on the primary guide rail 2, and a limiting plate 203 is fixedly provided on the sliding seat 201 of the primary guide rail 2. The limiting baffle 202 and the limiting plate 203 cooperate to restrict the sliding seat 201 from exceeding the travel along the sliding groove of the primary guide rail 2.
[0021] Furthermore, the upper and lower ends of the slide groove of the secondary guide rail 3 are respectively provided with a first limiting plate 302 and a second limiting plate 303, which are used to limit the slider 301 of the secondary guide rail 3 from exceeding the stroke along the slide groove of the secondary guide rail 3.
[0022] Furthermore, the primary guide rail 2 and the trolley boom 1 are detachably connected by a clamp.
[0023] Furthermore, the slide length of the primary guide rail 2 is 1.4-1.6m, the slide length of the secondary guide rail 3 is 0.8-1.1m, the height of the safety guardrail of the suspended platform 5 is 1.2m, and the sum of the guide rail length and the guardrail height is less than the cylinder extension distance of 3m, with a safety height of 0.2m reserved from the top plate.
[0024] Furthermore, the lower part of the side wall of the suspended basket 5 is hinged to the end of the hydraulic rod of the hydraulic cylinder 4 via a hinge seat 6.
[0025] Furthermore, the top of the suspended basket 5 is equipped with an anti-smashing baffle 501 to prevent falling rocks and other foreign objects from injuring the workers.
[0026] Furthermore, the bottom of the suspended basket 5 is provided with a storage groove 502, which has a U-shaped structure to facilitate workers to step on it, and can hold pallets and tools.
[0027] The aforementioned hydraulic cylinder 4 is a multi-stage cylinder with a multi-stage telescopic structure, a telescopic distance greater than 3m and a thrust greater than 5T, such as the UDZ type single-acting multi-stage hydraulic cylinder.
[0028] The operation process of the above-mentioned device is as follows: During construction, when the hydraulic system drives the hydraulic cylinder 4 to extend, it moves the suspended platform 5. At this time, the suspended platform 5 moves the slider 301 along the secondary guide rail 3. When the slider 301 moves to the bottom of the secondary guide rail 3, the slider 301 hits the second limit plate 303 and stops moving. At this time, the hydraulic cylinder 4 continues to extend, driving the sliding seat 201 on the primary guide rail 2 to move. When the sliding seat 201 moves to the bottom, the limit baffle 202 hits the limit plate 203, stopping the lifting and lowering of the suspended platform 7. At this time, the suspended platform 7 is at its lowest position. When the workers enter, the hydraulic cylinder 4 retracts, and the suspended platform 5 begins to rise. The slider 301 moves first, then the sliding seat 201 moves, and the platform retracts step by step until the workers reach the top of the tunnel.
