[0034] In order to make the person skilled in the art to which the present application belongs more clearly understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor are within the scope of protection of the present application.

[0035] The two top covers of the open carriage are oppositely arranged along the length direction of the carriage, the rear end of the top cover is connected with the carriage, and the front end of the top cover is provided with a sliding seat provided with a mounting structure of a male or female head. In this way, when the two top covers are closed to each other to close the opening, the male head and the female head are connected, so as to avoid the sliding of the top cover during the movement of the carriage.

[0036] In order to facilitate the opening or closing of the top cover, an opening and closing mechanism is arranged beside the railway track, and an opening and closing rod is arranged beside the sliding seat. The opening and closing mechanism can contact the side surface of the opening and closing rod. By the running of the carriage along the track and the sliding of the top cover relative to the sliding rail of the carriage, the opening of the open carriage is opened or closed.

[0037] Because the railway track itself can not be straight, for example, some positions are arc-shaped, therefore the length direction of the carriage itself can not be consistent with the extension direction of the track when the carriage moves along the track to the side of the opening and closing mechanism, and there is an included angle between the two, therefore when the opening and closing mechanism exerts the opening and closing force on the top cover along the extension direction of the track, the slide can be subjected to a component force along the width direction of the carriage, and the side pressure rim of the vertical limiting wheel can slide and rub against the side of the slide rail to generate a very large frictional resistance.

[0038] The first aspect of the present application provides a top cover of a transport vehicle, which is slidably installed on two slide rails of a carriage of the transport vehicle, can reduce the resistance in the sliding process of the top cover relative to the carriage of the transport vehicle, reduce noise, and improve the environment.

[0039] The present application will be described below in combination with the drawings and with reference to specific embodiments:

[0040] Please refer to Figure 3 The top cover 1000 provided by the present application includes a cover body 200 and a slide 100.

[0041] The cover body 200 is the main structure for covering the carriage 2000, which can prevent the rain from falling on the goods in the carriage 2000, and can also inhibit the dust in the case of granular goods such as coal powder in the carriage 2000, and improve the environment.

[0042] The slide 100 is a structure for connecting two top covers 1000 of the carriage 2000. Generally, the slide 100 is provided with a mounting position 140 for mounting a connecting structure 150. In the two slides 100 connected to each other, the connecting structure 150 of one slide 100 is a male head, and the connecting structure 150 of the other slide 100 is a female head. When the two top covers 1000 are close to each other, the male head and the female head are connected, thereby realizing the connection of the two top covers 1000. The slide 100 corresponds to the slide rail 2100 one by one, and the two slides 100 are installed on both sides of the cover body 200 along the width direction of the carriage 2000, thereby improving the stability of the cover body 200 during the sliding process relative to the slide rail 2100 of the carriage 2000. The slide 100 is close to one side of the cover body 200 along the length direction of the carriage 2000, that is, the slide 100 is arranged on the operation side of the cover body 200. The opening and closing mechanism 3000 on the ground acts on the operation side to realize the sliding of the cover body 200 relative to the carriage 2000, and open or close the carriage 2000.

[0043] Please refer to Figure 4 , Figure 5 and Figure 6The slide 100 comprises a supporting assembly 110 and a limiting assembly 120. The supporting assembly 110 can support the cover 200. The supporting assembly 110 comprises a support 111 and a walking wheel 112. The walking wheel 112 is installed on the support 111 and rolls on the top surface of the corresponding slide rail 2100. In this way, the resistance during the movement of the cover 200 relative to the slide rail 2100 can be reduced, and the opening and closing of the cover 200 can be more convenient. The limiting assembly 120 comprises a bracket 121 and a lateral limiting wheel 122. The lateral limiting wheel 122 is rotatably installed on the bracket 121. The bracket 121 is connected to the support 111. In this way, the connection between the lateral limiting wheel 122 and the support 111 is achieved. The lateral limiting wheel 122 rolls on the inner side or the outer side of the corresponding slide rail 2100. In this way, the slide 100 can limit the cover 200 in the width direction of the carriage 2000 and avoid the left and right deviation of the cover 200 relative to the slide rail 2100.

[0044] Since the lateral limiting wheel 122 is located on one side of the support 111 in the length direction of the carriage 2000 and is installed on the support 111 through the bracket 121, the limiting assembly 120 can be directly installed on the original support 111 of the slide 100. The original stepped vertical limiting wheel 113 can be replaced by the vertical limiting wheel 113 with the same diameter to achieve the functions of lateral limiting and vertical limiting. At the same time, the friction is reduced, the noise is reduced, and the environment is improved. The modification process is simple and the cost is low. If the lateral limiting wheel 122 with the same diameter is directly installed in the original support 111 of the slide 100, the support 111 needs to be modified. The size of the slide 100 is not large, and the operable space of the support 111 is small, which is time-consuming and laborious.

[0045] In addition, since the lateral limiting wheel 122 is located outside the support 111, the diameter of the lateral limiting wheel 122 can be selected as needed, i.e., a large-diameter limiting wheel or a small-diameter limiting wheel can be selected. Therefore, the versatility of the lateral limiting wheel 122 is improved.

[0046] In some embodiments, referring to Figure 5 The bracket 121 comprises a connecting plate 121b and two mounting arms 121a. The two mounting arms 121a are oppositely arranged on the connecting plate 121b in the height direction. The lateral limiting wheel 122 is rotatably installed between the two mounting arms 121a. The connecting plate 121b is connected to the support 111. Figure 5 and Figure 7 The mounting arm 121a is provided with a first positioning portion 1213. The support 111 is provided with a second positioning portion 113. The first positioning portion 1213 and the second positioning portion 113 are matched.

[0047] In the modification process, the support 121 can be connected with the lateral limiting wheel 122 first to form a whole, and then the limiting assembly 120 as a whole is positioned with the support 111, and then the support 121 is connected with the support 111, so that the process is more convenient, and the installation precision of the lateral limiting wheel 122 is higher.

[0048] In other embodiments, the support 121 can be directly connected with the support 111, for example, welded or screwed, etc., and the connection of the limiting assembly 120 and the support 111 can still be realized.

[0049] In some embodiments, among the first positioning part 1213 and the second positioning part 113, one is a positioning gap 1214, for example, a positioning through slot, and the other is a positioning piece 114, so as to realize the positioning of the support 121 and the support 111, and improve the installation precision of the lateral limiting wheel 122. The combination structure of the positioning gap 1214 and the positioning piece 114 is simple to process and easy to realize.

[0050] Please refer to Figure 5 In some embodiments, when the mounting arm 121a is provided with the positioning gap 1214 and the support 111 is provided with the positioning piece 114, the mounting arm 121a includes an installation part 1211 and a connecting part 1212 arranged at an angle, the lateral limiting wheel 122 is rotatably mounted on the installation part 1211, the connecting part 1212 is connected to the connecting plate 121b, and the positioning gap 1214 is located at the connection between the installation part 1211 and the connecting part 1212. The angle between the installation part 1211 and the connecting part 1212 can be used to form the positioning gap 1214. The support 111 is connected with an L-shaped positioning plate, the L-shaped positioning plate constitutes the positioning piece 114 and matches the positioning gap 1214. The support 111 is generally inverted U-shaped and has a side plate, and the L-shaped positioning plate can make full use of the space at the end of the inverted U-shaped support 111. In some embodiments, the angle between the installation part 1211 and the connecting part 1212 can be set to 90° to match the L-shaped positioning plate and occupy less space. In other embodiments, the angle between the installation part 1211 and the connecting part 1212 can be set to 80° or 85°, etc., which is not limited in the application.

[0051] In some embodiments, the lateral limiting wheel 122 is provided with two, and the two lateral limiting wheels 122 are located on both sides of the support 111 along the length direction of the vehicle compartment 2000, so as to simultaneously limit the front end and the rear end of the slide rail 100 in the lateral direction, balance the pressure, and have better limiting effect.

[0052] In some embodiments, the inner side and the outer side of the slide rail 2100 are each provided with a lateral limiting wheel 122, for example, four lateral limiting wheels 122, two of which are in rolling engagement with the inner side of the slide rail 2100, and the other two are in rolling engagement with the outer side of the slide rail 2100, further reducing the friction between the slide 100 and the slide rail 2100. The four lateral limiting wheels 122 are located at the four corners of the slide 100, and in the case of using a large-diameter limiting wheel, the center axis of the lateral limiting wheel 122 is further away from the support 111 in the length direction and the width direction of the carriage 2000, improving the stability of the slide 100 during sliding along the slide rail 2100.

[0053] In some embodiments, referring to Figure 8 , the slide rail 2100 includes a first sliding part 2101 and a second sliding part 2102 arranged in sequence from top to bottom, the first sliding part 2101 extends beyond the second sliding part 2102 along both sides of the width direction of the carriage 2000, the walking wheel 112 walks on the top surface of the first sliding part 2101, and the lateral limiting wheel 122 is in rolling contact with the inner side / outer side of the first sliding part 2101; the slide 100 further includes a vertical limiting wheel 113 in rolling contact with the first sliding part 2101, and the portions of the first sliding part 2101 extending beyond the second sliding part 2102 along both sides of the width direction of the carriage 2000 are each provided with a vertical limiting wheel 113, the vertical limiting wheel 113, the walking wheel, and the lateral limiting wheel 122 are staggered to achieve the arrangement of each wheel without interfering with each other.

[0054] In some embodiments, referring to Figure 6 , the support assembly 110 is provided in plurality, the plurality of support assemblies 110 are arranged in sequence along the extension direction of the slide rail 2100, and any two adjacent supports 111 are hinged by a hinge shaft 132 to adapt to the arc-shaped design of the slide rail 2100 at the end of the carriage 2000, so that the slide 100 can smoothly pass through the arc-shaped slide rail 2100. The limiting assembly 120 is provided in two, and the two limiting assemblies 120 are located on both sides of the plurality of support assemblies 110 along the length direction of the carriage 2000, so that the front end and the rear end of the slide 100 cannot deviate.

[0055] Based on the same technical concept as the first aspect, the second embodiment of the present application provides a transport vehicle, which includes the top cover 1000 of any one of the embodiments of the first aspect.

[0056] Referring to Figure 9 , the transport vehicle includes a carriage 2000, and the top cover 1000 is slidingly connected to the slide rail 2100 of the carriage 2000.

[0057] The transport vehicle with the top cover 1000 can improve the service life of the sliding seat 100, and can reduce the opening and closing force of the vehicle top cover 1000, so as to improve the working state of the top cover 1000 and improve the service life, and has good practicability.
