[0020] The embodiments of the present application 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 are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0021] As Figures 1-2As shown, the double-track car supporting device of the embodiment of the present application comprises a car support 1, a connecting rod 2 and a handrail, the two ends of the connecting rod 2 are respectively connected with a car support 1, the handrail is connected on the connecting rod 2 and extends along a first direction, the first direction is perpendicular to the extending direction of the connecting rod 2, the car support 1 has a clamping groove for clamping the track and a supporting surface 11 for supporting the wheel, and the bottom wall of the clamping groove and the supporting surface 11 are both provided with anti-skid pads.

[0022] It can be understood that, since the anti-skid pads are arranged on the clamping groove and the supporting surface 11 of the car support 1, the contact surfaces between the car support 1 and the track and the wheel are all increased in friction and anti-skid effect, thereby the supporting stability can be improved and the risk of overturning or falling off the track can be reduced, and the handrail is externally arranged on the connecting rod 2, so that the car support 1 can be operated through the handrail when being supported, without the need of stretching the hand into the lower part of the vehicle body for supporting, so that the risk of hand clamping can be avoided and the personal safety of the operator can be ensured.

[0023] The double-track car supporting device of the embodiment of the present application, the supporting surface 11 of the car support 1 and the clamping groove matched with the track are both provided with anti-skid pads, compared with the traditional iron-to-iron contact of the car support 1, the anti-skid effect of the present application is good, the risk of overturning or falling off the track is reduced, and the operator can complete the position adjustment of the car support 1 through the handrail when supporting, without the need of stretching the hand into the lower part of the vehicle body for operation, so that the risk of hand clamping can be avoided and the personal safety of the operator can be ensured.

[0024] Specifically, as shown, Figure 1 The car support 1 comprises a body and a clamping part connected at the bottom of the body, the clamping part comprises an inner clamping plate 12 and an outer clamping plate 13 arranged at intervals in the length direction of the connecting rod 2, the clamping groove is formed between the inner clamping plate 12 and the outer clamping plate 13, and the end surface of the body away from the clamping part is the supporting surface 11.

[0025] Preferably, the anti-skid pads are made of waste belts, which is convenient for material taking and recycling of waste resources.

[0026] Further, the outer clamping plate 13 and the inner clamping plate 12 are both provided with connecting holes, and the connecting holes on the two clamping plates are opposite. It should be noted that the underground transportation equipment includes various types and models of vehicles, and the track size corresponding to the adaptation of different vehicles is also different, so that the connecting holes are arranged on the inner and outer clamping plates, the overall width of the car support 1 can be changed on one side of the car support 1 according to the tracks of different widths, so as to meet the adaptability of different size tracks, improve the flexibility of use, and reduce the application cost.

[0027] For example, when the track width exceeds a single car support 1, a car support 1 can be installed on one side of the outer side plate, and a wider clamping groove can be formed between the inner clamping plate 12 and the outer clamping plate 13 of the two car supports 1 to adapt to the width of the track.

[0028] It can be understood that by constructing the car support 1 into an assembly structure, the car support 1 does not need to be redesigned and produced when adapting to tracks of different width sizes, thereby reducing the overall cost.

[0029] In some embodiments, as shown in Figure 1 The support surface 11 is an arc-shaped surface recessed towards the clamping portion. In this way, the arc-shaped support surface 11 can better fit the outer contour of the wheel, and the fit between the two is more secure, and the stability of the support is higher.

[0030] Further, the support surface 11 is provided with a groove for clamping the non-slip pad. In this way, after the non-slip pad is arranged in the groove, the groove can limit the non-slip pad, avoiding the problem of slipping and shifting of the non-slip pad in long-term use.

[0031] In some embodiments, as shown in Figure 2 The connecting rod 2 includes a fixed section and a telescopic section, and the telescopic section is telescopic relative to the fixed section in the length direction of the connecting rod 2. It should be noted that the distance between the double tracks corresponding to different vehicles is different, and by setting the connecting rod 2 into a telescopic structure, the distance between the two car supports 1 can be adaptively adjusted according to the specific interval of the double tracks, so as to achieve the purpose of adapting to the tracks, that is, the double-track car support device of the present application can adapt to double tracks of different intervals, improve the flexibility of application, and does not need to be redesigned and produced according to the track interval, thereby reducing the cost.

[0032] Further, as shown in Figure 2 The telescopic section includes a first telescopic section 22 and a second telescopic section 23, and the first telescopic section 22 and the second telescopic section 23 are connected to the two ends of the fixed section respectively, and the outer ends of the first telescopic section 22 and the second telescopic section 23 are connected with the car supports 1. In other words, the middle part of the connecting rod 2 is the fixed section, and the telescopic sections are symmetrically arranged on both sides, and when adjusting the distance between the two car supports 1, the first telescopic section 22 or the second telescopic section 23 can be adjusted on one side, or the first telescopic section 22 and the second telescopic section 23 can be adjusted at the same time, which can be determined according to the operation demand.

[0033] Alternatively, the fixed section is a hollow pipe with internal threads, and the inner ends of the first telescopic section 22 and the second telescopic section 23 are fitted in the hollow pipe and are provided with external threads. In other words, the first telescopic section 22 and the second telescopic section 23 are connected with the fixed section by threads, which is convenient for telescopic adjustment, reliable in connection and simple in structure.

[0034] In some embodiments, the connecting rod 2 is threadedly connected with the car support 1. Thus, the connecting rod 2 is detachable from the car support 1, and when a single car support 1 is damaged, the damaged car support 1 can be conveniently disassembled, repaired and replaced without the need to re-manufacture the entire car support device.

[0035] In some embodiments, as shown in FIG. 3, the handrail rod 3 is connected at a middle position in the length direction of the connecting rod 2. Thus, the two car supports 1 are symmetrically arranged relative to the handrail rod 3, and the operation balance is better and the structure is more stable. Figure 1

[0036] In some embodiments, first and second auxiliary rods are connected between the handrail rod 3 and the connecting rod 2, and the first and second auxiliary rods are respectively located on two sides of the handrail rod 3. Thus, the two auxiliary rods can further improve the connection reliability between the handrail rod 3 and the connecting rod 2, and any one of the auxiliary rods, the handrail rod 3 and the connecting rod 2 can form a stable triangular structure, and the overall structural strength of the car support device is large and the service life is long.
