[0003] Some areas use internal combustion engine locomotives to dispatch train cars. However, the internal combustion engine locomotives are expensive, and the use and maintenance costs are also high.

[0004] Some areas also use iron oxen to pull train cars. The iron oxen is connected to the front end of the train car, and the iron oxen is pulled by the steel wire rope to drive the train car to run. The steel wire rope connected to the iron oxen needs to be laid along the center line of the train track, so the steel wire rope, guide pulley and steel wire rope supporting roller in this part need to be arranged on the inner side of the track, and need to be installed below the track surface to avoid interference with the train car, so a pit needs to be dug below the track surface to install the equipment, which not only increases the difficulty of civil construction, but also brings difficulties to track laying, and the daily maintenance of the equipment also has safety hazards.

[0005] Therefore, a device is needed to achieve fixed-point and fixed-quantity traction of freight train cars, which not only has low cost, but also has the key advantage that the traction components are independent of the train and the track, and do not interfere with them, so that the maintenance of the equipment is safer and more reliable.

[0025] The core of the present application is to provide a wire rope set type train traction device. In order to enable those skilled in the art to better understand the present application scheme, the present application will be further described in detail below in combination with the drawings and specific embodiments.

[0026] As Figures 1 to 3 shown, the wire rope set type train traction device is composed of two sets of traction devices symmetrically arranged on the outside of the train track, which together pull the train carriage; each set of device includes a closed loop wire rope 1, a branch wire rope set 2, a tail wheel 3, a driving wheel 4, a motor 5, a tail wheel adjusting device, a ground type heavy hammer tensioning device, a spring tightener and a guide wheel assembly 9.

[0027] The tail wheel 3 and the driving wheel 4 are in a straight line and are respectively installed at the head and tail ends of the train 10, the closed loop wire rope 1 is a closed loop, and the closed loop wire rope 1 is installed on the driving wheel 4 and the tail wheel 3. The motor 5 is connected with the driving wheel 4, and the motor 5 drives the driving wheel 4 to rotate.

[0028] The branch wire rope set 2 includes a wire rope, a rope hook 21, a rope buckle 22, a rope hook fixing block 23, a three-way rope ring 24 and a wire rope adjuster 25. The rope hook fixing block 23 is fixedly connected to the train carriage 10, the rope hook 21 is fixedly connected to the rope hook fixing block 23, the rope buckle 22 is connected with the rope hook 21, one end of the wire rope is connected with the rope buckle 22, and the other end is connected with the upper part of the closed loop wire rope 1 through the three-way rope ring 24, and the wire rope adjuster 25 is installed on the wire rope.

[0029] The upper part of the closed loop wire rope 1 branches out the branch wire rope set 2, and the branch wire rope sets 2 of the two sets of systems symmetrically arranged on the outside of the train track 10 are respectively connected to the two sides of the carriage. Because the lateral forces on both sides cancel out, there is no lateral component force to ensure that the carriage is uniformly stressed. The train carriage traction stroke is determined by the stroke of the branch wire rope set 2 reciprocating on the upper part of the closed loop wire rope 1.

[0030] The branch steel wire rope group 2 is connected with the side of the compartment at the front end of the train 10. The number of the steel wire ropes contained in the branch steel wire rope group 2 is determined by the size of the traction force. The larger the traction force is, the more the number of the steel wire ropes contained in the branch steel wire rope group 2 is. Generally, the number is 2-5.

[0031] The motor 5 drives the rotation of the driving wheel 4, drives the operation of the closed loop steel wire rope 1, and further drives the reciprocating movement of the train 10.

[0032] The tail wheel adjusting device comprises an adjusting screw 61 and a sliding rail 62. The adjusting screw 61 is connected with the tail wheel 3 and drives the tail wheel 3 to slide along the sliding rail 62. The tail wheel adjusting device adjusts the distance between the tail wheel 3 and the front driving wheel 4, thereby adjusting the initial tension of the steel wire rope. The sliding rail 62 is used to reduce the adjusting resistance.

[0033] The ground type heavy hammer tensioning device comprises a pulley 71, a roller slide 72 and a counterweight 73. The pulley 71 is installed on the roller slide 72, and the closed loop steel wire rope 1 is connected with the counterweight 73 through the pulley 71. The ground type heavy hammer tensioning device is arranged on the ground and is used to absorb the deformation of the closed loop steel wire rope 1, and can effectively contain the rope. The counterweight 73 is used to naturally tension the steel wire rope. One set of ground type heavy hammer tensioning device is arranged at the front end and the rear end. The pulley 71 of the ground type heavy hammer tensioning device is provided with a guide roller. The guide roller moves up and down in the roller slide 72, thereby improving the stability and safety of the tensioning process.

[0034] The spring rope tensioner comprises a rope sleeve 81 and a tension spring 82. One end of the tension spring 82 is fixedly connected to the ground, and the other end is connected with the lower part of the closed loop steel wire rope 1 through the rope sleeve 81. The spring rope tensioner is arranged between the two groups of guide roller assemblies 9. The spring rope tensioner is used to absorb the deformation of the lower part of the closed loop steel wire rope 1. The tension spring 82 installed on the ground is used to tension the lower part of the closed loop steel wire rope 1. The rope sleeve 81 is arranged on the upper part of the spring rope tensioner and is sleeved on the outer side of the steel wire rope. The rope sleeve is of a split type structure and is convenient to install and disassemble. The inner diameters of the two ends of the rope sleeve 81 are respectively arranged as trumpet mouths. When the closed loop steel wire rope 1 is pulled downward by the tension spring 82, the rope sleeve 81 can follow the deformation of the steel wire rope and naturally form a V angle.

[0035] The guide roller assembly 9 is installed on the ground and is connected with the closed loop steel wire rope 1, thereby supporting the lower part of the closed loop steel wire rope 1.

[0036] The traction device of the application comprises two sets of traction devices symmetrically arranged outside the train track and used to jointly drive the train compartment. The traction device does not interfere with the train track, is safe and reliable in maintenance, has the advantages of simple structure, flexible arrangement, small occupied space and low investment cost.

[0037] The above merely describes preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art, according to the technical solution and inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
