[0064] Figure 1FIG. 1 is a schematic diagram of the structure of a rail trolley according to an embodiment of the utility model applied to a monorail track. Figure 1 As shown, the rail trolley 10 of the present invention can travel along the monorail track 500, and at the same time, some equipment can be carried on the frame assembly 200 of the rail trolley 10, so as to meet the requirements of construction operations along the track. Using the rail trolley 10 of the present invention to carry construction equipment can reduce a lot of manpower and material resources, and can also improve construction efficiency.

[0065] The rail trolley 10 of the utility model includes a traveling device 100 and a supporting device 400, wherein the traveling device 100 includes a traveling wheel group 110 and a frame assembly 200, the traveling wheel group 110 is arranged below the supporting assembly, and the traveling wheel group 110 is pivotally connected to the frame assembly 200, so that driven by the traveling wheel group 110, the frame assembly 200 and the related equipment thereon can move along the monorail track 500 together with the traveling wheel group 110, and the construction personnel can operate the related equipment on the frame assembly 200 to perform operations during the traveling of the rail trolley 10 or during the interval stop time.

[0066] In order to enable the rail trolley 10 to move along the monorail track 500 without tipping over, the rail trolley 10 of the present invention is further provided with a support device 400, in which support members are provided, and the support members are respectively connected to the frame assembly 200 and the monorail track 500, so as to reduce the side tilt of the frame assembly 200 during the movement or during the interval stop time.

[0067] The support member can be arranged on one side of the frame assembly 200, and the support member is respectively connected to the frame assembly 200 and the monorail track 500 on one side of the frame assembly 200 to play a supporting role; the support device 400 can also be provided with multiple support members, and the multiple support members are respectively arranged on both sides of the frame assembly 200. On both sides of the frame assembly 200, the support members are respectively connected to the frame assembly 200 and the monorail track 500, so that the rail trolley 10 can stably walk or park along the monorail track 500 without tipping over.

[0068] Figure 2 This is a schematic diagram of a rail trolley according to an embodiment of the utility model capable of carrying construction equipment, such as Figure 2 As shown, the frame assembly 200 of the rail trolley 10 of the utility model can be provided with relevant equipment. Figure 2 A rod-shaped support member 610 is firstly provided on the frame assembly 200. After the rod-shaped support member 610 is fixedly connected to the frame assembly 200, the relevant equipment is hung on the rod-shaped support member 610. The relevant equipment can move along the monorail track 500 or stop at any position of the monorail track 500 together with the rail trolley 10.

[0069] Auxiliary equipment that facilitates construction operations, such as a power balancing device or a position adjustment device 300, can also be provided on the frame assembly 200, so that the operator can easily adjust the position of related equipment or provide assistance for the operator's construction operations. Among them, the related equipment provided on the frame assembly 200 includes a torque wrench or a bolt wrench 600, etc.

[0070] The power-assisted balancing device or the position adjustment device 300 can at least drive the working equipment to reciprocate along the first direction A to meet the construction work requirements.

[0071] It should be noted that the torque wrench or bolt wrench 600 and related equipment on the frame assembly 200 of the rail trolley of the utility model are special equipment in the field of rail transportation, and their total weight is tens of kilograms. Relying on manual transportation will seriously consume the physical strength of the operators and will seriously reduce the efficiency of the construction work. The use of the rail trolley 10 of the utility model can well solve the above problems. Whether it is in the process of walking along the monorail track 500 or temporarily stopping on the monorail track 500, the rail trolley 10 of the utility model can stably carry the related equipment.

[0072] Figure 3A This is a schematic structural diagram of a running device of a rail cart according to an embodiment of the utility model; Figure 3B FIG. 1 is a schematic structural diagram of the running device of the rail trolley according to another embodiment of the utility model from another perspective, as shown in FIG. Figure 3A and Figure 3B As shown, combined with Figure 2 The frame assembly 200 in the rail trolley 10 of the embodiment of the utility model includes a frame 210, and a support area 220 is provided on the frame 210, and the support area 220 is used to carry working equipment used for construction operations.

[0073] like Figure 3A and Figure 3B As shown, the traveling wheel group 110 of the rail trolley of the present embodiment includes a first wheel group 111 and a second wheel group 112, the first wheel group 111 and the second wheel group 112 are both pivotally connected to the frame 210, and the first wheel group 111 and the second wheel group 112 are spaced apart in the forward direction of the rail trolley 10, and the supporting area 220 on the frame 210 is arranged between the first wheel group 111 and the second wheel group 112, so that under the support of the first wheel group 111 and the second wheel group 112, the working equipment on the supporting area 220 can be stably fixed on the frame 210, and the frame 210 will not overturn due to the excessive weight of the related equipment used for the construction work, and at the same time, under the support of the supporting device 400, the rail trolley 10 carrying the working equipment can stably travel on the monorail track 500 or park on the monorail track 500.

[0074] like Figure 3A and Figure 3B As shown, the first wheel group 111 and the second wheel group 112 are respectively arranged at the two ends of the frame 210. Such an arrangement can set more connection positions on the frame 210, increase the carrying capacity of the frame 210, and enable the frame 210 to carry more working equipment for construction operations.

[0075] It should be noted that the traveling device 100 of the rail trolley 10 of the utility model can be provided with a plurality of traveling wheel groups 110, and the plurality of traveling wheel groups 110 are arranged below the frame assembly 200 for supporting the frame assembly 200, and at the same time, the plurality of traveling wheel groups 110 are pivotally connected to the frame assembly 200, and can drive the frame assembly 200 to move along the monorail track 500.

[0076] In one embodiment of the rail cart of the present invention, the frame 210 includes a plurality of cross beams and a plurality of longitudinal beams, and the plurality of cross beams and the plurality of longitudinal beams are sequentially connected to form the frame 210. The frame 210 with a beam structure can improve the overall rigidity and strength of the frame 210. Even if the weight of the relevant equipment used for construction work on the frame 210 is large, or the impact force of the relevant equipment during operation is large, the frame 210 can still maintain a high stability.

[0077] like Figure 3A and Figure 3B As shown, in one embodiment of the utility model, the frame assembly 200 includes a sheet metal part 211, and the sheet metal part 211 is formed into a frame 210 through a bending process. It can be clearly seen from the figure that the frame 210 after the sheet metal part 211 is bent includes a plurality of planes extending in different directions, and the plurality of planes are connected to act as supporting beams. This structure can also improve the rigidity and strength of the frame 210, so that the frame 210 has higher stability during the construction process.

[0078] Figure 4 Schematic diagram of the structure of the support device of the rail trolley of the embodiment of the utility model, as shown in Figure 4 As shown, in the rail trolley 10 of this embodiment, a supporting device 400 is also provided. Figure 2 The support device 400 can be arranged in a direction perpendicular to the forward movement of the rail trolley 10, and some parts of the support device 400 are fixedly connected to the frame 210. The support device 400 plays the role of a support beam in the rail trolley 10, which is beneficial to improving the stability of the frame 210.

[0079] Figure 5 FIG. 1 is a structural schematic diagram of the support device of the rail trolley of an embodiment of the utility model from another perspective, as shown in FIG. Figure 5As shown, the support device 400 includes a first support assembly 410, which is connected to the frame assembly 200. The first support assembly 410 is provided with a first support member 411 and a second support member 412. The first support member 411 and the second support member 412 are respectively located on both sides of the monorail track 500 and support the frame assembly 200 in different directions.

[0080] The rail trolley 10 in this embodiment has a first support member 411 and a second support member 412 respectively disposed on both sides of the monorail track 500 , and the first support member 411 and the second support member 412 support the frame assembly 200 in different directions, thereby improving the stability of the frame assembly 200 .

[0081] Among them, the first support member 411 and the second support member 412 can support the frame assembly 200 when the rail trolley 10 moves along the monorail track 500, and can also support the frame assembly 200 when the rail trolley 10 is parked on the rail trolley 10.

[0082] It can be understood that the first support member 411 and the second support member 412 can be supported on both sides of the monorail track 500, such as supported on the rail head 510, the rail body 520 or the rail bottom 530 of the monorail track 500; the first support member 411 and the second support member 412 can also be supported on the ground or other supporting objects on both sides of the monorail track 500 to reduce the phenomenon of the rail trolley 10 tipping over.

[0083] Figure 6 FIG. 4 is a schematic structural diagram of a support device of a rail trolley according to an embodiment of the present utility model, wherein a first support assembly 410 and a second support assembly 420 are shown. Figure 6 As shown, the support device 400 in the rail trolley 10 of this embodiment further includes a second support assembly 420 , and the second support assembly 420 and the first support assembly 410 work together to support the frame assembly 200 .

[0084] Specifically, the second support assembly 420 is provided with a connecting rod 421 and a rotating wheel 422, one end of the connecting rod 421 is pivotally connected to the rotating wheel 422, and the other end of the connecting rod 421 is connected to the first support member 411, wherein the outer peripheral surface of the rotating wheel 422 is arranged close to the side of the monorail track 500 to support the frame assembly 200.

[0085] In the rail trolley 10 of this embodiment, the first support member 411 is arranged close to the side of the monorail track 500 through the rotating wheel 422 in the second support assembly 420, and supports the frame assembly 200 on one side of the frame assembly 200.

[0086] Similarly, on one side of the monorail track 500 where the second support member 412 is set, a second support assembly 420 connected to the second support member 412 is arranged, and the second support assembly 420 includes a connecting rod 421 and a rotating wheel 422, one end of the connecting rod 421 is pivotally connected to the rotating wheel 422, and the other end of the connecting rod 421 is connected to the second support member 412, wherein the outer peripheral surface of the rotating wheel 422 is set close to the side of the monorail track 500 to support the frame assembly 200.

[0087] The rail cart in this embodiment adopts an implementation method of supporting the frame assembly 200 by setting the rotating wheel 422 close to the monorail track 500, which can realize that the rotating wheel 422 contacts the monorail track 500 in a rolling manner, thereby reducing excessive rigid friction between the support device 400 and the monorail track 500, thereby extending the service life and use cycle of some components in the support device 400.

[0088] In one embodiment of the utility model, the outer circumference of the rotating wheel 422 in the second support assembly 420 is clearance-matched with the side of the monorail track 500. By adopting the clearance-matching method, the gap between the outer circumference of the rotating wheel 422 and the side of the monorail track 500 can make up for the error generated in the processing or assembly process of the second support assembly 420 or the rail trolley 10, thereby avoiding the phenomenon that the rotating wheel 422 of the rail trolley 10 and the side of the monorail track 500 cannot be properly installed and matched.

[0089] Furthermore, by setting a gap between the outer circumferential surface of the rotating wheel 422 and the side surface of the monorail track 500, the rail trolley 10 can make the rotating wheel 422 in the second support assembly 420 contact the side surface of the monorail track 500 only when it is parked on the monorail track 500, thereby supporting the frame assembly 200; when the rail trolley 10 is traveling on the monorail track 500, the contact between the rotating wheel 422 in the second support assembly 420 and the side surface of the monorail track 500 can be reduced, thereby reducing the friction between the rotating wheel 422 and the monorail track 500.

[0090] More specifically, the outer circumference of the rotating wheel 422 of the second support assembly 420 is clearance-matched with the lower end surface of the rail head 510 of the monorail track 500; the outer circumference of the rotating wheel 422 of the second support assembly 420 can also be clearance-matched with the rail body 520 of the monorail track 500; the outer circumference of the rotating wheel 422 of the second support assembly 420 can also be clearance-matched with the upper end surface of the rail bottom 530 of the monorail track 500; the above three different implementations can all achieve the purpose of supporting the frame assembly 200.

[0091] In one embodiment of the utility model, the outer peripheral surface of the rotating wheel 422 in the second supporting assembly 420 of the rail trolley 10 abuts against the side of the monorail track 500, that is, whether the rail trolley 10 is in a state of traveling on the monorail track 500 or parked on the monorail track 500, the rail trolley 10 is supported in at least two directions, one of which is the contact surface between the traveling wheel group 110 and the monorail track 500, and the other is the contact surface where the rotating wheel 422 of the second supporting assembly 420 abuts against the side of the monorail track 500. With the support in two directions, the rail trolley 10 can have a high stability at any time.

[0092] When the second support assemblies 420 are provided on both sides of the monorail track 500, the rail trolley 10 can be supported in at least three directions, so that the rail trolley 10 has higher stability.
