DETAILED DESCRIPTION

[0026] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0027] According to the following Figure 1-6 A cable pulling vehicle 100 and a cable pulling device according to an embodiment of the present invention will be described.

[0028] The cable pulling device includes a cable pulling vehicle 100, a pulling cable track and a driving chain, wherein the driving chain is located in the pulling cable track and connected to the cable pulling vehicle 100 so as to drive the cable pulling vehicle 100 to slide forward and backward along the pulling cable track. The cable pulling vehicle 100 includes a body 110, a connector 120, a first pulling arm 131, a second pulling arm 132 and a guide roller 140.

[0029] The connector 120 is used to connect the body 110 and the first traction arm 131 and the second traction arm 132. The connector 120 includes a rotating portion 121 and a connecting portion 122. The rotating portion 121 is hinged to the body 110. By virtue of the hinged relationship between the rotating portion 121 and the body 110, the connector 120 can rotate around the first axis, that is, the central axis of the hinge shaft between the rotating portion 121 and the body 110 coincides with the first axis.

[0030] The first traction arm 131 and the second traction arm 132 are arranged opposite to each other, and each of the first traction arm 131 and the second traction arm 132 is hinged to the connection part 122. By utilizing this hinged relationship, the first traction arm 131 and the second traction arm 132 can both rotate around the second axis. In other words, the central axis of the hinge shaft of each of the first traction arm 131 and the second traction arm 132 and the connection part 122 coincides with the second axis. Thus, by connecting the sleeve 120, each of the first traction arm 131 and the second traction arm 132 can swing around the first axis relative to the body 110, and can also swing around the second axis.

[0031] The first axis is perpendicular to the second axis, for example, the first axis extends in the up-down direction, and the second axis extends in the left-right direction. It is understandable that the first axis and the second axis can also extend in other directions, preferably, one of the first axis and the second axis extends in the up-down direction, and the other extends in the left-right direction.

[0032] The two ends of the guide roller 140 are rotatably connected to the first traction arm 131 and the second traction arm 132 respectively. Since the first traction arm 131 and the second traction arm 132 are connected to the body 110, the guide roller 140 is rotatably connected to the body 110. The rotatable connection means that the guide roller 140 can rotate relative to the body 110 around its central axis. The purpose of rotatably connecting the guide roller 140 to the body 110 is to facilitate the guide roller 140 to wind the cable.

[0033] Specifically, during the operation of the cable tug vehicle 100, the cable is wound around the guide roller 140, and the bending point of the cable is limited on the guide roller 140. The guide roller 140 drives the cable to follow the coal mining machine at a certain proportional speed along with the cable tug vehicle 100, ensuring that the cable is always in a flat state, avoiding the overlapping of multiple layers of cables, and eliminating the need for staff to follow and monitor, saving manpower and material resources, reducing the maintenance cost of the cable, and improving the safety of the coal mining system. As an example, the sliding direction of the cable tug vehicle 100 in the embodiment of the present invention is the front-to-back direction, and the cable tug vehicle 100 can slide back and forth in the front-to-back direction to realize the above-mentioned cable tug function. The front-to-back direction is as follows: Figure 1 As indicated by the arrow in .

[0034] The cable towing vehicle according to the embodiment of the present invention includes a connector, which is hinged to the body through a rotating part, and is hinged to the first traction arm and the second traction arm for connecting the guide roller through the connecting part, so that the guide roller can rotate relative to the body around the first axis and the second axis, wherein the first axis and the second axis are perpendicular to each other, so that the guide roller realizes a "flexible connection" with the body. When the cable towing vehicle is bumped left and right or up and down due to the instability of the towing cable track or foreign objects on the towing cable track during operation, the guide roller can swing left and right and up and down relative to the body, thereby offsetting the mechanical energy generated by the bump or vibration, and having a certain buffering effect on the guide roller and the cable wound on the guide roller. The guide roller can also be adjusted to a certain position by swinging at a small angle according to the stress condition of the cable, thereby improving the adaptive performance and passing capacity of the cable towing vehicle.

[0035] Therefore, the cable towing vehicle according to the embodiment of the present invention has the advantages of strong adaptive performance and good passing capacity.

[0036] Below the joint Figure 1-Figure 6 The cable pulling vehicle according to the embodiment of the present invention is described in detail. Figure 2 As shown, the cable pulling vehicle 100 includes a body 110, a connector 120, a first traction arm 131, a second traction arm 132 and a guide roller 140. The first traction arm 131, the second traction arm 132 and the guide roller 140 are all located in front of the body 110, and the rotating portion 121 of the connector 120 is located at the rear side of the connecting portion 122 of the connector 120 and is connected thereto. The first axis extends in the up-down direction, and the second axis extends in the left-right direction.

[0037] like Figure 4As shown, the connecting portion 122 includes a first connecting arm 1221 and a second connecting arm 1222 that are opposite to each other in the left-right direction. The first connecting arm 1221 and the second connecting arm 1222 both extend forward in the front-back direction, wherein the first traction arm 131 is hinged to the first connecting arm 1221, and the second traction arm 132 is hinged to the second connecting arm 1222. As an example, Figure 2 As shown, the first traction arm 131 is hinged to the first connecting arm 1221 through the first pin shaft 151, and the second traction arm 132 is hinged to the second connecting arm 1222 through the second pin shaft 152. In this embodiment, the guide roller 140 is located between the first connecting arm 1221 and the second connecting arm 1222 in the left-right direction, and the central axis of the guide roller 140 extends in the left-right direction.

[0038] Specifically, Figure 6 As shown, the first pin shaft 151 passes through the first traction arm 131 and the first connecting arm 1221 and is connected to the first nut 161, and the second pin shaft 152 passes through the second traction arm 132 and the second connecting arm 1222 and is connected to the second nut 162. The first pin shaft 151 serves as the rotation center axis of the first traction arm 131, and the second pin shaft 152 serves as the rotation center axis of the second traction arm 132.

[0039] It can be understood that in other embodiments, when the second axis extends in the up-down direction, the first connecting arm 1221 and the second connecting arm 1222 can be opposite to each other in the up-down direction, and the guide roller 140 is located between the first connecting arm 1221 and the second connecting arm 1222 in the up-down direction, and its central axis extends in the up-down direction.

[0040] Furthermore, the connecting portion 122 is located between the first traction arm 131 and the second traction arm 132 in the left-right direction, and the central axis of the first pin shaft 151, the central axis of the second pin shaft 152 and the second axis coincide with each other. Since the second axis extends in the left-right direction, the central axis of the first pin shaft 151 and the central axis of the second pin shaft 152 both extend in the left-right direction and are located on the same straight line. In this way, the structure of the cable pulling vehicle 100 is more reasonable.

[0041] In other embodiments, the first traction arm 131 and the second traction arm 132 may be located between the first connecting arm 1221 and the second connecting arm 1222 in the left-right direction, that is, the connecting portion 122 sandwiches the first traction arm 131 and the second traction arm 132 .

[0042] like Figure 3As shown, the body includes a hinge shaft 111, the central axis of which extends in the up-down direction, that is, the central axis of the hinge shaft 111 is the first axis, and a through hole 1211 is provided on the rotating part 121, and the hinge shaft 111 is fitted in the through hole 1211 so that the connector 120 can rotate around the first axis. The hinge shaft 111 serves as the central axis of rotation of the rotating part 121.

[0043] Furthermore, the body 110 includes a front baffle 112, which is a baffle on the front side of the body 110. As an example, Figure 5 As shown, a chamber 1121 and a mounting hole 1123 communicating with the chamber 1121 are provided in the front baffle 112, and the front end of the chamber is opened to form an opening 1122. The mounting hole 1123 is located above the chamber 1121. The hinge shaft 111 includes a shaft portion 1111 and a limiting portion 1112 connected to each other, and the shaft portion 1111 extends into the chamber 1121 through the mounting hole 1123, that is, the shaft portion 1111 passes through the chamber 1121 of the mounting hole 1123 from top to bottom. The size of the limiting portion 1112 of the hinge shaft 111 is larger than the size of the mounting hole 1123, so that the limiting portion 1112 abuts against the portion of the front baffle 112 located near the mounting hole 1123 to limit the hinge shaft 111. Thus, a portion of the hinge shaft 111 is located in the cavity 1121 , and the rotating portion 121 extends from front to rear through the opening 1122 into the cavity 1121 to cooperate with a portion of the hinge shaft 111 .

[0044] Preferably, a limiting hole 1124 is provided on the wall surface of the chamber 1121 opposite to the mounting hole 1123, that is, the limiting hole 1124 is provided below the chamber 1121. The hinge shaft 111 passes through the chamber 1121 and then extends into the limiting hole 1124 and abuts against the bottom of the limiting hole 1124. The limiting hole 1124 makes the installation of the hinge shaft 111 more stable.
