Description

Technical Field

[0001] The utility model relates to the technical field of underground operation, in particular to a towing device of an underground remote-controlled scraper. Background Art

[0002] A remote-controlled scraper is an underground earth-moving machine that uses a bucket to shovel ore and loads ore and slag into the bucket for transportation. The remote control personnel usually operate the scraper in a safe area to shovel ore. When the remote-controlled scraper enters the goaf to shovel ore, if the roof rock is unstable and falls down, it will bury the remote-controlled scraper, or if the scraper fails, the scraper will be unable to leave the goaf. The cost of a remote-controlled scraper is relatively high. Once it fails or is buried and difficult to drag out, it can only be abandoned in the goaf, resulting in huge losses and affecting the mining progress. Therefore, once the scraper fails, or the roof of the goaf collapses and buries the scraper, making it impossible for the scraper to leave the goaf, it is necessary to manually enter the goaf and use a steel cable to connect the accident vehicle to another scraper, and use the power of another scraper to drag the faulty scraper out of the goaf. Since there is no anchor rod or anchor net support in the goaf, the surrounding rock is extremely unstable and small-scale roof collapse often occurs. It is extremely dangerous for personnel to enter the goaf and use steel cables to pull out the faulty vehicle. The processing time is long and the safety of personnel cannot be reliably guaranteed.

DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.

[0019] In the description of the present invention, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0020] In the description of the present utility model, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed" etc. are understood as not including the number itself, and "above", "below", "within" etc. are understood as including the number itself. If there are descriptions of the first, second and other similar terms, they are only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0021] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0022] like Figure 1 and Figure 2 As shown, a trailer device for an underground remote-controlled scraper described in an embodiment of the present application includes a connecting member 3 and a traction member 4 that can be connected to each other. The connecting member 3 is installed on the tail 11 of the remote-controlled scraper 1 to be towed, and the traction member 4 is installed on the bucket 21 of another remote-controlled scraper 2 that can operate normally.

[0023] When the underground remote-controlled scraper is buried, the buried remote-controlled scraper is damaged due to the crushing of the surrounding rock and ore on the top of the goaf, or the buried remote-controlled scraper cannot be autonomously separated from the goaf, and when the remote-controlled scraper fails, it is necessary to control another remote-controlled scraper 2 that can operate normally to enter the goaf to tow the buried or failed remote-controlled scraper (i.e., the remote-controlled scraper 1 to be towed). Therefore, the above-mentioned attachment 3 can be installed at the tail of each remote-controlled scraper, and the traction member 4 can be installed on the bucket 21 of another remote-controlled scraper 2 that can operate normally. Personnel use a remote control machine in a safe position to operate a remote-controlled shovel loader 2 that can operate normally to enter the goaf, and operate the bucket 21 of the remote-controlled shovel loader 2 that can operate normally to clean the ore at the tail 11 of the remote-controlled shovel loader 1 to be towed, so that the connecting part 3 at the tail 11 of the remote-controlled shovel loader 1 to be towed is exposed so that it can be better connected with the traction part 4 on the bucket 21 of the remote-controlled shovel loader 2 that can operate normally. The personnel operate the bucket 21 of the normally operating remote-controlled scraper 2 to extend it under the tail 11 of the remote-controlled scraper 1 to be towed, and then lift the arm of the bucket 21 of the normally operating remote-controlled scraper 2, so that the weight of the tail of the remote-controlled scraper 1 to be towed is pressed on the bucket 21 of the normally operating remote-controlled scraper 2, reducing the friction between the wheels of the remote-controlled scraper 1 to be towed and the ground during the towing process. At the same time, pressing the weight of the remote-controlled scraper 1 to be towed on the bucket 21 of the normally operating remote-controlled scraper 2 can also ensure the tight connection between the attachment 3 and the traction member 4, so as to ensure that the attachment 3 and the traction member 4 will not separate and fall off when the remote-controlled scraper 1 to be towed is towed. After that, the personnel operate the normally operating remote-controlled scraper 2 to tow the remote-controlled scraper 1 to be towed to a safe position. The embodiment of the present application installs a hooking part 3 on the tail 11 of the remote-controlled scraper 1 to be towed, and installs a traction part 4 on the bucket 21 of another remote-controlled scraper 2 that can operate normally, so that personnel can operate the remote-controlled scraper 2 that can operate normally in a safe position to tow the remote-controlled scraper 1 to be towed, ensuring the safety of the operating personnel while reducing the losses caused by the remote-controlled scraper being buried or failing and unable to be towed out, thereby effectively improving the towing efficiency and mining efficiency. The towing device described in the embodiment of the present application also has the advantages of simple structure, reliable performance, and low cost.

[0024] Under extreme conditions, a remote-controlled scraper 2 that can operate normally may not have enough power to tow the buried or faulty remote-controlled scraper 1 to be towed. In this case, multiple remote-controlled scrapers 2 that can operate normally can be connected in series, and adjacent remote-controlled scrapers 2 that can operate normally can still be connected through the connecting parts 3 and the traction parts 4 to increase the power during towing.

[0025] As an optional embodiment, the hooking member 3 may have a protruding portion protruding downward, and the traction member 4 may have a sleeve hole 42 adapted to the protruding portion. The traction member 4 may be sleeved on the protruding portion of the hooking member 3 through the sleeve hole 42. Such a structural form facilitates the rapid connection and separation between two adjacent remote-controlled scrapers, and can effectively prevent the hooking member 3 and the traction member 4 from separating and falling off when lifting and towing the remote-controlled scraper 1 to be towed.

[0026] In addition, the protruding portion of the hanging member 3 can also be inclined in the direction away from the tail portion 11, or the lower end of the protruding portion of the hanging member 3 has a transverse protrusion protruding in the direction away from the tail portion 11 to form a shape similar to a hook. These two structural forms can further ensure that the hanging member 3 and the traction member 4 are not easy to separate and fall off.

[0027] To ensure the normal operation of the remote-controlled scraper bucket 21, the traction member 4 can be detachably connected to the normally operating remote-controlled scraper bucket 21. In this way, when the remote-controlled scraper is not carrying out hauling operations, it is not necessary to install the traction member 4 on the bucket 21, thereby facilitating the operation of the bucket 21.

[0028] The traction plate 41 can be detachably connected to the bucket 21 of the normally operating remote-controlled scraper by bolts 5. At this time, corresponding through holes 43 can be provided at corresponding positions on the traction member 4 and the bucket 21 to facilitate the connection of the bolts 5.

[0029] As an optional implementation, Figure 2 As shown, the traction member 4 may include a traction plate 41, and the traction plate 41 is detachably connected to the bucket 21 of the normally operating remote-controlled scraper, that is, the through hole 43 is provided on the traction plate 41. At the same time, the socket hole 42 is also provided on the traction plate 41.

[0030] In order to facilitate the connection between the hooking member 3 and the traction member 4, the sleeve hole 42 has a guide portion on the side away from the bucket 21, so that the sleeve hole 42 on the traction member 4 can guide the protrusion to enter the sleeve hole 42 during the process of being fitted onto the protrusion of the hooking member 3. The guide portion can be a shape that gradually protrudes from both sides to the middle in a direction away from the bucket 21, such as an arc shape or a V shape.

[0031] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] The above preferred embodiments shall not be regarded as limiting the present invention, and the protection scope of the present invention shall be subject to the scope defined by the claims. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications shall also be regarded as the protection scope of the present invention.
