Description

Technical Field

[0001] The utility model relates to a novel folding bracket for a connecting rod of a mining locomotive. Background Art

[0002] Sockets are provided at both ends of the body of the electric locomotive in a coal mine. The sockets are provided with sockets for plugs to be inserted. Pin holes are opened on the sockets above and below the sockets, and pins are inserted into the pin holes. When the electric locomotive in a coal mine transports special materials, a bulky connecting rod connection is required. The plugs at both ends of the connecting rod are provided with pin holes, and the plugs are inserted into the sockets of the sockets. The pin holes of the plug and the socket overlap and are penetrated by the pins together, so as to realize the connection and fixation between adjacent electric locomotives in coal mines.

[0003] In the prior art, when a heavy connecting rod is used to connect adjacent underground coal mine motors, a worker is required to remove the pin on the corresponding socket of the front vehicle, lift the front end of the connecting rod, insert the plug of the connecting rod into the socket of the socket of the front locomotive, and then insert the pin into the pin hole of the plug and the socket at the same time to achieve the connection of the front end of the connecting rod;

[0004] Then the worker tries to lift the other end of the connecting rod and pull out the pin on the socket of the rear locomotive at the same time. The locomotive driver starts the rear locomotive so that the socket of the socket is put on the plug at the rear end of the connecting rod, and then inserts the pin into the pin holes of the plug and socket at the same time to connect the rear end of the connecting rod.

[0005] During the process of connecting the rear end of the connecting rod, the personnel stand between the adjacent coal mine underground electric locomotives and continuously lift the heavy connecting rod, which is labor-intensive and poses great safety risks. The prior art urgently needs a new type of folding bracket for connecting rods of mine locomotives that is safe and reliable to reduce the labor of workers and reduce safety risks. Summary of the invention

[0006] The technical problem to be solved by the utility model is how to overcome the above-mentioned defects of the prior art and provide a new folding bracket for a connecting rod of a mining locomotive.

[0007] In order to solve the above technical problems, a new type of folding bracket for a mining locomotive connecting rod is provided, which is characterized in that it includes a left frame, a right frame and a chain, the left frame includes two parallel diagonal struts and a cross bar connecting the two parallel diagonal struts, the tops of the two parallel diagonal struts of the left frame are folded outward to form an outer folding rod, and an upper horizontal axis is provided between the roots of the two outer folding rods, the right frame includes two parallel diagonal struts and a cross bar connecting the two parallel diagonal struts, and the tops of the two parallel diagonal struts of the right frame are provided with hinge rings; the hinge rings at the tops of the two parallel diagonal struts of the right frame are respectively sleeved on the upper horizontal axis, and a downward curved arc-shaped support beam is connected between the two outer folding rods, and the chain is composed of a plurality of chain links connected in sequence.

[0008] One end of the chain is fixed on the cross bar of the left frame, and a hanging column pointing outward and upward is provided in the middle of the cross bar of the right frame, or one end of the chain is fixed on the cross bar of the right frame, and a hanging column pointing outward and upward is provided in the middle of the cross bar of the left frame. The hanging column can be selectively inserted into an appropriate chain link on the chain to adjust and fix the height of the arc-shaped support beam.

[0009] With this design, there is no need to continuously lift the connecting rod with manpower during the movement of the locomotive, which is labor-saving and convenient, and it is safer as there are no workers in the adjacent locomotive room.

[0010] With such a design, the two sides of the arc-shaped support beam are respectively provided with oblique straight shaft sections, and the two oblique straight shaft sections are respectively covered with rotatable supporting wheels to support the matching locomotive connecting rod. With such a design, when the matching locomotive connecting rod moves on the new folding bracket for the mining locomotive connecting rod, rolling friction occurs with the supporting wheels, with small resistance and labor saving.

[0011] The utility model discloses a novel folding bracket for a connecting rod of a mining locomotive, which has a simple structure, is safe and convenient, and is suitable for use when a connecting rod is used to connect a mining locomotive. BRIEF DESCRIPTION OF THE DRAWINGS
