Embodiment Construction
[0029] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0030] like Figure 1-6 As shown, a multi-catch sleeper spreader with uniform distribution function includes two balance beams 1 and main beams 14 on both sides fixedly connected with the balance beams 1 . Seven sleeper spreaders are slidingly connected to the main beam 14 .
[0031] Each sleeper hanger includes a beam 11, and a centering device is provided on the beam 11 to make the center line of the sleeper coincide with the center line of the sleeper hanger. The centering device includes a pair of centering adjustment seats 21 and a connecting shaft 24 fixedly connected to the beam 11, and each centering adjustment seat 21 is provided with two mounting holes 29 in the vertical direction. The centering adjustment seat 21 is hinged with the scissors arm 20 through the mounting hole 29; the upper part of the centering adjustment seat 21 is provided wi...

The invention discloses a multi-grab sleeper sling with a uniform distribution function. A plurality of sleeper sling bodies are slidably connected to main beams; each sleeper sling body is separatelyconnected with a driving motor capable of enabling the sleeper sling bodies to horizontally move on the main beams; each sleeper sling body comprises a cross beam, and a centering device for enablingthe center line of sleepers to coincide with the center line of the sleeper sling bodies is arranged on the cross beams; a position sensor is fixedly connected to each sleeper sling body; detection blocks with the same number as the position sensors are slidably connected to the main beam on one side; the position sensors are matched with the detection blocks one by one for use; the multi-grab sleeper sling with the uniform distribution function comprises controllers; the input ends of the controllers are electrically connected with the position sensors; and the output ends of the controllersare electrically connected with the corresponding driving motors. According to the multi-grab sleeper sling with the uniform distribution function, the positions of the sleeper sling bodies are adjusted through the centering devices, and the placing intervals among the sleepers are adjusted through the position sensors, the detection blocks, the driving motors and the controllers after lifting; and the plurality of sleepers can be lifted each time for accurate uniform distribution, and the working efficiency and the precision are high.
Description
technical field [0001] The invention relates to the technical field of railway construction equipment, in particular to a multi-catch sleeper spreader with the function of uniform distribution. Background technique [0002] In railway construction, sleeper laying is one of the core links. There are various types of sleepers, and the distance between different railway sleepers is also different. In fact, when the sleepers leave the factory, they are stacked in rows and columns, and there are well-proportioned sleepers between each row, and each column is basically evenly distributed. The conventional technological process is: when the project is confirmed, special spreaders are customized, hoisted to the track one by one, assembled into a rail row by manual marking, and then lay the track. Although there are different spreaders for grabbing sleepers, they are all grabbing one by one, and this method has low efficiency and precision. Contents of the invention [0003] The...
