Description

Technical Field

[0001] The invention relates to the technical field of hydraulic support transportation, and in particular to a straddle-type support transport vehicle. Background Art

[0002] The crawler hydraulic support transport vehicle has the advantages of large carrying capacity, strong grip, low noise, and the ability to turn on the spot. The crawler walking device also increases the contact area with the ground, making the support vehicle have good driving performance, less damage to the road surface, enhanced obstacle crossing ability, and strong terrain adaptability.

[0003] Hydraulic support is an indispensable supporting equipment for comprehensive mechanized coal mining in underground working faces. The transportation of hydraulic supports is an important operation in the working face. The space in the underground working face is limited, the transport vehicle cannot turn around, and the transport vehicle can only operate in one direction. When the transport vehicle carrying the hydraulic support enters the working face, the transport vehicle lowers the hydraulic support and exits. Due to limited space, the transport vehicle needs to wait for the hydraulic support to be placed before it can leave the working face. The transportation and installation cycle of the hydraulic support is long, the transportation flexibility is poor, and it cannot better meet the underground transportation operations. Summary of the invention

[0004] In view of this, an object of the present invention is to provide a straddle-type support transporter to solve the problems raised in the background technology.

[0005] In order to achieve the above purpose, the technical solutions adopted are as follows:

[0006] The straddle-type support transporter comprises two crawler machines arranged side by side, each of which is equipped with a power assembly to provide driving power for the crawler machines, and the upper parts of the two crawler machines are fixedly connected by a straddle-type support;

[0007] It also includes a chain, one end of which is rotatably connected to the power assembly, and the other end of the chain is equipped with a hook for hooking the hydraulic support, and the hooks are distributed in pairs and located on opposite sides of the two crawler machines.

[0008] As a further improvement of the present invention, one end of the chain is connected to the driving sprocket, the chain passes around the driven sprocket installed on the straddling bracket, and the other end of the chain hangs down and is connected to the hook.

[0009] As a further improvement of the present invention, the driving sprocket is installed on the crawler machine, the driving sprocket is an umbrella-shaped structure, the central axis of the driving sprocket is fixedly connected to one end of the connecting rod, the other end of the connecting rod is connected to the telescopic end of the hydraulic rod, and the other end of the hydraulic rod is rotatably connected to the crawler machine.

[0010] As a further improvement of the present invention, the telescopic end of the hydraulic rod is rotatably connected to the connecting rod, and the bottom of the hydraulic rod is rotatably connected to the crawler machine.

[0011] As a further improvement of the present invention, two symmetrically arranged guide wheels are installed on the inner side of the crawler machine, and a chain passes through between the two guide wheels to play a guiding and limiting role.

[0012] As a further improvement of the present invention, the hydraulic rod is connected to the oil cylinder in the power assembly, and the oil cylinder is connected to the hydraulic rod through a hydraulic control valve.

[0013] The beneficial effects of the present invention are:

[0014] The transporter moves to the position of the hydraulic support, the hydraulic rod retracts the hook below, and the hook is hung on the lifting ear of the base of the hydraulic support. The hydraulic rod extends and rotates the active sprocket through the connecting rod to lift the hydraulic support. There is no need to turn around in the narrow lane. The hydraulic support can be put down to exit the lane and continue to transport the next hydraulic support. It will not affect the installation and placement of the hydraulic support on the working surface, thereby improving the installation efficiency of the hydraulic support.
