Description

Technical Field

[0001] The utility model belongs to the technical field of rail sleeper laying, and in particular relates to a sleeper laying device for railway construction. Background Art

[0002] The technical background of the sleeper laying device for railway construction is to solve the efficiency and precision problems of sleeper laying during railway construction. In the traditional railway laying method, a large amount of manpower is required to carry and lay sleepers, which not only has high labor intensity, but also has low laying efficiency and high error rate. With the development of technology, sleeper laying devices have been developed to improve the efficiency and quality of railway construction. The problems existing in the sleeper laying devices for railway construction are mainly poor stability and insufficient friction when grabbing and clamping sleepers. Most of the existing devices use grabbing claws to clamp sleepers, but in actual operation, since the grabbing claws are not accurately clamped at the center of the sleepers, this leads to poor stability of the clamps, insufficient friction, and unstable center of gravity. Such problems are particularly obvious when the sleepers are laid under the rails for adjustment, which often causes the clamping of the sleepers to slip, seriously affecting the quality and efficiency of laying. Utility Model Content

[0003] In order to overcome the problem that the existing sleeper laying device for railway construction does not accurately clamp the center of the sleeper, resulting in poor clamping stability, insufficient friction and unstable center of gravity, which makes it easy for the sleeper to slip when it is laid under the rail and adjusted.

[0004] The technical solution of the utility model is: a sleeper laying device for railway construction, including a sleeper handling assembly and a five-axis adjustment mechanical arm assembly; the output end of the five-axis adjustment mechanical arm assembly is provided with the sleeper handling assembly, and the sleeper handling assembly is transmission-connected with the output end of the five-axis adjustment mechanical arm assembly; the sleeper handling assembly includes a frame, a clamping claw, a hydraulic claw driver, a hydraulic pressing clamp driver, and a lower pressing strip; clamping claws are provided on both sides of the lower end of the frame, and the clamping claws are rotationally connected with the shaft sleeve of the lower end surface of the frame.

[0005] Preferably, the clamping claws are driven by a hydraulic claw driver to rotate around a shaft sleeve connected to the frame, thereby realizing the clamping and carrying function of the two clamping claws on the sleepers. After the sleeper is clamped by the clamping claws, the hydraulic pressure clamp driver drives its output end to drive the lower pressure bar to press downward, and the lower pressure bar applies pressure downward on the sleeper to increase the clamping friction between the sleeper and the clamping claws, thereby preventing the clamping claws from rotating horizontally to drive the sleeper to adjust its posture and causing it to loosen. This solves the problem of existing sleeper laying devices for railway construction, because their grabbing claws do not accurately clamp the center when clamping the sleepers, resulting in poor clamping stability, insufficient friction and unstable center of gravity, which makes it easy for the sleepers to slip when they are laid under the rails and adjusted.

[0006] Preferably, a hydraulic jaw driver is arranged above the clamping jaws, and the hydraulic jaw driver is arranged inside the frame, and the output end of the hydraulic jaw driver is hydraulically connected to the movable end of the clamping jaws.

[0007] Preferably, a hydraulic jaw driver is arranged above the clamping jaws, and the hydraulic jaw driver is arranged inside the frame, and the output end of the hydraulic jaw driver is hydraulically connected to the movable end of the clamping jaws. The clamping jaws are driven by the hydraulic jaw driver to rotate around the bushing connected to the frame, so as to realize the clamping and handling function of the two clamping jaws for the sleeper. After the sleeper is clamped by the clamping jaws, the hydraulic pressing clamp driver drives its output end to drive the pressing strip to press downwards, and the pressing strip applies a downward pressure to the sleeper, thereby increasing the clamping friction force between the sleeper and the clamping jaws, and further preventing the problem of loosening when the clamping jaws rotate horizontally to drive the sleeper to adjust its posture.

[0008] Preferably, a pressing strip is arranged at the lower end of the hydraulic pressing clamp driver, and the pressing strip is hydraulically connected to the output end of the hydraulic pressing clamp driver for lifting and lowering.

[0009] Preferably, the five-axis adjustment robotic arm assembly includes a base platform, a first adjustment arm, a second adjustment arm, a third adjustment arm, a fourth adjustment arm, and a rotation driver; the base platform is fixedly arranged on an external crawler vehicle; the upper end shaft end of the base platform is provided with the first adjustment arm; the shaft end on one side of the first adjustment arm is provided with the second adjustment arm.

[0010] Preferably, a third adjustment arm is arranged on one side above the second adjustment arm, and the third adjustment arm is rotationally connected to the second adjustment arm for adjustment.

[0011] Preferably, a fourth adjustment arm is arranged on one side in front of the third adjustment arm, and the fourth adjustment arm is rotationally connected to the third adjustment arm for adjustment; a rotation driver is fixedly arranged in front of the output end of the fourth adjustment arm, and the output end of the rotation driver is rotationally connected to the frame. The five-axis adjustment robotic arm assembly is connected to the external crawler vehicle, so as to adjust the posture and handling actions of the sleeper handling assembly through five-axis adjustment activities, greatly improving the flexibility of posture adjustment for sleeper handling and laying.

[0012] Advantages of the present utility model:

[0013] 1. The existing sleeper laying device for railway construction has a problem that when its gripping claws hold the sleepers, they do not precisely grip the center, resulting in poor clamping stability of the fixture, insufficient friction, and unstable center of gravity. This causes the problem that the sleepers are prone to clamping slippage during the adjustment under the railway tracks. By driving the clamping claws to rotate around the bushing connected to the frame through the hydraulic claw driver, the clamping and handling functions of the two clamping claws for the sleepers are realized. After the sleepers are clamped by the clamping claws, the hydraulic downward clamping driver drives its output end to drive the downward pressing bar to press downward, and the downward pressing bar applies downward pressure to the sleepers to increase the clamping friction between the sleepers and the clamping claws, thereby preventing the problem of loosening when the clamping claws rotate horizontally to drive the sleepers for attitude adjustment; it solves the problem of the existing sleeper laying device for railway construction that when its gripping claws hold the sleepers, they do not precisely grip the center, resulting in poor clamping stability of the fixture, insufficient friction, and unstable center of gravity, causing the problem that the sleepers are prone to clamping slippage during the adjustment under the railway tracks.

[0014] 2. Through the setting of the five-axis adjustment robotic arm assembly, the five-axis adjustment robotic arm assembly is connected to the external tracked vehicle, so as to adjust the attitude and handling actions of the sleeper handling assembly through five-axis adjustment activities, greatly improving the flexibility of attitude adjustment for sleeper handling and laying.
