Technical Field

[0001] The utility model relates to the field of small material transportation in complex environments, and in particular comprises a cable-drawn and guided crawler-type transport trolley. Background Art

[0002] The difficulty of transporting materials on steep slopes has always been one of the problems restricting engineering construction. Traditional vertical hoists have limited applicability, while detour transportation costs are high. Manual lifting is unsafe and difficult to control. Therefore, for the transportation of materials on steep slopes, it is necessary to propose a dedicated transportation tool suitable for this working condition to overcome the above problems. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a cable-drawn and guided crawler-type transport trolley.

[0004] This cable-traction-guided crawler transport trolley has a cable fixing buckle at the front end of the transport trolley and a traction bracket at the top of the slope. The cable fixing buckle is anchored to one end of the cable, and the other end of the cable is connected to the traction bracket.

[0005] A hydraulic support system and a crawler system are provided under the transport trolley, and the hydraulic support system is provided in front of the crawler system; a rear baffle is fixedly provided at the rear end of the transport trolley, and a front baffle is detachably installed above the transport trolley, and the cargo is placed between the front baffle and the rear baffle.

[0006] Preferably, the traction bracket includes an equipment foundation, on which a winch and a pulley frame are provided, and the pulley frame is provided with a movable fixed pulley. One end of the cable connected to the traction bracket is turned from the movable fixed pulley to the winch, and the winch is used to control the length of the cable.

[0007] Preferably, the movable fixed pulley is fixed and moved vertically on the pulley frame to control the angle and slope matching of the cable between the movable fixed pulley and the cable fixing buckle.

[0008] Preferably, the winch is arranged on the side of the pulley frame away from the transport trolley, and a pulley frame cable foundation is provided on the side of the equipment foundation away from the transport trolley. The pulley frame cable foundation is anchored to the soil through a ground lock anchor rod, and a pulley frame cable is provided between the pulley frame cable foundation and the top of the pulley frame.

[0009] Preferably, the cable fixing buckle includes an upper caliper and a lower caliper, the front ends of the upper caliper and the lower caliper overlap, and a cable sleeve is provided through them, and one end of the cable connected to the cable fixing buckle is passed through the cable sleeve.

[0011] The beneficial effects of the utility model are:

[0012] 1) The utility model designs a cable-traction guided crawler transport trolley. Compared with traditional crawler transport machinery, the traction bracket can provide pulling force to the transport trolley through the cable, so that the transport trolley has a stronger transport capacity. At the same time, it can also serve as a guide device for the traction trolley, thereby enhancing the stability of the trolley when traveling in a high and steep slope environment.

[0013] 2) The utility model provides a movable fixed pulley so that the connection position of the cable on the pulley frame can be adjusted. By adjusting the height of the movable fixed pulley, the inclination angle of the cable can be matched with the inclination angle of the steep slope, thereby ensuring the traction effect of the cable tension on the transport trolley to the greatest extent. The transport trolley has a strong transport capacity and good applicability, and is particularly suitable for transporting materials on steep slopes in construction projects.

[0014] 2) The utility model connects one end of the cable to the transport trolley to a displacement alarm, and uses the displacement alarm to determine whether the cable is connected normally, and uses this as a basis to control the start of the hydraulic support system. When the cable slips, the transport trolley is temporarily fixed on the slope, thereby further improving the safety of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to the following embodiments. The following embodiments are provided solely to facilitate understanding of the present invention. It should be noted that, within the scope of the present invention, modifications may be made by a person skilled in the art without departing from the principles of the present invention. Such improvements and modifications are also within the scope of the claims of the present invention.

[0022] As an example, Figures 1 to 5 As shown, this cable-traction-guided crawler transport trolley has a cable fixing buckle 11 at the front end of the transport trolley 1, the unloading platform 3 is located on a high and steep slope, and a traction bracket 2 is provided on the top of the slope behind the unloading platform 3. The cable fixing buckle 11 and one end of the cable 22 are anchored and connected, and the other end of the cable 22 is connected to the traction bracket 2 at the top of the slope.

[0023] A hydraulic support system 14 and a crawler system are provided under the transport trolley 1. The crawler system includes a crawler shaft 13 and a rubber crawler 18, and is driven by the power system of the transport trolley 1. The power system can be but is not limited to an electric motor; the hydraulic support system 14 is provided on the front side of the crawler system.

[0024] A rear baffle 15 is fixedly mounted on the rear end of the transport trolley 1. A front baffle 17 is detachably mounted on the transport trolley 1. Cargo is placed between the front baffle 17 and the rear baffle 15 to limit lateral movement of the cargo. The front baffle 17 is detachable and can be removed when loading or unloading cargo. The cargo is secured with tie straps 16.

[0025] The cable fixing buckle 11 includes an upper caliper 112 and a lower caliper 113 . The front ends of the upper caliper 112 and the lower caliper 113 overlap and are penetrated by a cable sleeve 111 . One end of the cable 22 connected to the cable fixing buckle 11 is passed through the cable sleeve 111 .

[0026] A displacement alarm 114 is provided at one end of the cable 22 connected to the cable fixing buckle 11. This alarm is used to control the hydraulic support system 14. When the upper caliper 112 and the lower caliper 113 tightly clamp the cable 22, which is covered with the cable sleeve 111, the displacement alarm 114 is not pulled. When the connection between the cable 22 and the cable fixing buckle 11 loosens, the displacement alarm 114 is pulled and an alarm sounds. Upon receiving the alarm, the hydraulic support system 14 is activated, and the pop-up pressure head pushes down on the slope, thereby preventing the transport cart 1 from sliding down.

[0027] It should be noted that the parts in this embodiment that are the same or similar to those in the first embodiment can be referenced to each other and will not be described in detail in this application.

[0028] Example 2

[0029] As another embodiment, this second embodiment proposes, based on the first embodiment, a more specific cable-traction-guided crawler transport trolley.

[0030] The traction support 2 includes an equipment base 21, on which are mounted a winch 24 and a pulley frame 25. The pulley frame 25 is equipped with a movable fixed pulley 23. A cable 22, connected to one end of the traction support 2, is transferred from the movable fixed pulley 23 to the winch 24. The winch 24 is used to control the length of the cable 22. When the power provided by the crawler system of the transport trolley 1 is insufficient, the cable 22 is continuously retracted, exerting a pulling force on the transport trolley 1. When the power provided by the crawler system is sufficient, the winch 24 retracts the cable 22, providing a certain degree of guidance and ensuring safety in the event that the transport trolley 1 accidentally slips.

[0031] The movable fixed pulley 23 is fixed and moved vertically on the pulley frame 25 to control the angle and slope matching of the cable 22 between the movable fixed pulley 23 and the cable fixing buckle 11 .

[0032] A winch 24 is located on the side of the pulley frame 25 away from the transport trolley 1. A pulley frame cable foundation 27 is located on the side of the equipment foundation 21 away from the transport trolley 1. This foundation is anchored to the soil via ground anchors 28 and has sufficient pullout resistance. A pulley frame cable 26 is installed between the pulley frame cable foundation 27 and the top of the pulley frame 25 to enhance its anti-overturning capability.

[0033] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
