Description

Technical Field

[0001] This application relates to the field of lifting device technology, such as a crane boom and a trolley for delivering parts of railway freight cars. Background Technology

[0002] The descriptions in this section are provided only as background information relating to this disclosure and do not constitute prior art.

[0003] With the continuous increase in railway freight volume, the quality and efficiency of whole-vehicle maintenance face higher requirements. Currently, the valve delivery trolley used on-site is just a flatbed electric tricycle. This vehicle lacks a dedicated area for valve delivery boxes and brake hose storage. During use, the valve delivery boxes must be manually loaded onto the vehicle, and unloading also requires manual handling. Valves are typically heavy and irregularly shaped, making manual loading, unloading, handling, and stacking not only inefficient but also physically demanding for operators, posing significant occupational safety risks. Existing fixed lifting equipment (such as gantry cranes) requires dedicated operating space and tracks, making effective integration with the flexible delivery trolley impossible. Temporarily constructed simple cranes are often structurally unstable, labor-intensive to operate, and difficult to precisely control the lifting, lowering, and placement of goods within the limited shelving space.

For example, "connection" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this disclosure according to the specific circumstances.

[0021] Unless otherwise stated, the term "multiple" means two or more.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0023] Combination Figure 1-5 As shown, this embodiment of the present disclosure provides a boom, including: a column 11, an electric winch 21, a first swing arm 13, a first guide wheel 12, a second guide wheel 15, a second swing arm 23, a third guide wheel 14, a fourth guide wheel 16, a lifting rope 17, and a handle 22; The column 11 has a hoisting rope through hole inside and is fixed to the vehicle body 19 or the base at the bottom. The column 11 is a tubular structure, such as a round tube or a square tube. The hole in the middle of the tube serves as a hoisting rope through hole for the hoisting rope 17 to pass through. The vehicle body 19 or the base has a through hole, which corresponds to the hoisting rope through hole and the electric winch 21.

[0024] The electric winch 21 is fixed to the vehicle body 19 or the base by a mounting plate; the electric winch 21 is a structure in which the motor drives the winch to rotate, which is a prior art in the field, and the winch rotates to retrieve and release the hoisting rope 17.

[0025] The first swing arm 13 is rotatably connected to the upper part of the column 11; the rear part of the first swing arm 13 is connected to the connecting pipe, and the connecting pipe is connected to the upper end of the column 11 through a bearing.

[0026] The first guide wheel 12 is located on the upper rear side of the first swing arm 13. The first guide wheel 12 is tangentially or closely fitted to the axis of the hoisting rope through hole, so that the hoisting rope 17 can smoothly bend into the hoisting rope through hole at the first guide wheel 12.

[0027] The second guide wheel 15 is located on the upper front side of the first swing arm 13; the hoisting rope 17 passes over the first guide wheel 12 from the top and then passes over the second guide wheel 15 from the bottom.

[0028] The second swing arm 23 is rotatably connected to the front end of the first swing arm 13; the rear end of the second swing arm 23 is provided with two connecting ears, which are rotatably connected to the front end of the first swing arm 13 via a rotating shaft.

[0029] The third guide wheel 14 is located on the upper rear side of the second swing arm 23; the hoisting rope 17 passes over the third guide wheel 14 from the top.

[0030] The fourth guide pulley 16 is located on the upper front side of the second swing arm 23; the hoisting rope 17 passes over the fourth guide pulley 16 from above. The pulley system consisting of the first guide pulley 12, the second guide pulley 15, the third guide pulley 14, and the fourth guide pulley 16 ensures a smooth transmission path and a reasonable bend angle for the hoisting rope 17. This design greatly reduces the frictional resistance between the rope and the structural components, making it easier and less strenuous for the operator to swing the boom using the handle 22.

[0031] The hoisting rope 17 has one end connected to the cargo via a connecting component 18, and the other end passes sequentially around the fourth guide wheel 16, the third guide wheel 14, the second guide wheel 15, and the first guide wheel 12 before passing through the hoisting rope hole and connecting to the electric winch 21. The connecting component 18 includes hooks, rings, claws, tensioners, slings, and other connecting parts.

[0032] Handle 22 is mounted on the second swing arm 23.

[0033] By integrating the electric winch 21 with a multi-joint swing arm and guide wheel system, electric lifting of valves (cargo) is achieved. The operator only needs to control the electric winch 21 and push the handle 22 to easily lift, move and place heavy objects, completely freeing manpower from heavy handling labor, significantly improving loading and unloading efficiency, and reducing labor intensity and safety hazards.

[0034] In some embodiments, the boom further includes: The first U-shaped frame 24 has its inner two ends rotatably connected to the first guide wheel 12 and the second guide wheel 15, and its lower side is connected to the first swing arm 13; the opening of the first U-shaped frame 24 is set downward.

[0035] The second U-shaped frame 25 is rotatably connected to the third guide wheel 14 and the fourth guide wheel 16 at both inner ends, and connected to the second swing arm 23 at the bottom. The opening of the second U-shaped frame 25 faces downward. By setting the first U-shaped frame 24 and the second U-shaped frame 25, the guide wheel assembly is concentrated above the swing arm, making the space below the swing arm and the shelf area open and unobstructed, which is convenient for the operator to observe and accurately stack the goods.

[0036] In some embodiments, the first swing arm 13 is straight, the second swing arm 23 is L-shaped, the first guide wheel 12 and the second guide wheel 15 are at the same height, the third guide wheel 14 and the fourth guide wheel 16 are at the same height, and the height of the third guide wheel 14 is higher than that of the first guide wheel 12.

[0037] This embodiment provides a trolley for delivering valve parts for railway freight cars, including: the boom described in any of the above embodiments.

[0038] In some embodiments, the railway freight car valve parts delivery trolley further includes a driver's area and a cargo area, wherein a rack is provided on the cargo area. A column 11 is located at the center of the rack. A first swing arm 13 is located above the rack.

[0039] In some embodiments, the shelf includes: Upper support platform 26, with a goods placement platform and a first goods placement slide on the upper part; The lower support platform 27 is connected to the upper support platform 26 via a support frame at the top and to the base or vehicle body 19 at the bottom. The upper part is provided with a second goods placement slide and a first goods placement slide.

[0040] In some embodiments, the first goods placement slide includes: The support plate is horizontally positioned and fixed to the support frame. The slide seat has a U-shaped structure and its lower part is connected to the support plate. The trachea placement slot 28 is equipped with a partition plate and is located inside the slide seat.

[0041] In some embodiments, the second goods placement slide includes: The slide rail is installed on the lower support platform 27; The slider is set within the slide rail; The tray 29 is connected to the slider at the bottom and has a groove for placing goods at the top; The first switch 31 is movably mounted on the support frame to prevent the tray 29 from sliding outward; A limiting plate is installed on the lower support platform to restrict the tray 29 from sliding inward.
