Detailed Embodiment

[0024] The following further describes the specific structure of the present utility model:

[0025] The monorail crane track installation and maintenance auxiliary device of the present utility model includes a load - carrying trolley 4, a carrying beam, a swing boom 8, a track - supporting swing arm 9, a lifting structure 7 and a track bracket 10; the load - carrying trolley 4 is arranged above and in front and behind of the carrying beam, and the load - carrying trolley 4 travels on the monorail crane track 2.

[0026] Two groups of load - carrying trolleys are installed on one group of carrying beams to realize the operation of the track installation and maintenance auxiliary device designed in this patent to reach the designated working position. The device designed in this patent is recommended to be used in combination with a pneumatic dispatching monorail crane. Compared with diesel and lithium - battery monorail cranes mainly used for carrying operations, the pneumatic dispatching monorail crane is mainly used in occasions with small load and temporary use. In addition, it has the advantages of simple structure and flexibility.

[0027] The carrying beam is used to fixedly install the track installation and maintenance auxiliary device designed in this patent; in addition, a chain motor is installed thereon as a power device to provide power for the operation of this device.

[0028] In this device, the rear end of the swing boom 8 is hinged to the lower part of the rear end of the carrying beam, the front end of the swing boom 8 is hinged to the track - supporting swing arm 9, the track - supporting swing arm 9 is provided with the track bracket 10 at its front end, the lower front end of the carrying beam is provided with the lifting structure 7, the lifting end of the lifting structure 7 is connected to the swing boom 8, the swing boom 8 and the track - supporting swing arm 9 are arranged at an obtuse angle when lifting the track bracket 10, the high position of the movement of the track bracket 10 is at the height of the track to be installed, and the pre - installed track 1 is placed on the track bracket 10. The lifting structure 7 realizes operations such as lifting and position adjustment of the swing boom 8 of this design device through the power device.

[0029] A pin positioning mechanism is provided between the swinging jib 8 and the track support swinging arm 9, and a pin positioning mechanism is provided between the track bracket 10 and the track support swinging arm 9. Baffles are provided on both sides of the track bracket 10, and fixing bolts are provided at the top of the baffles to connect the two side baffles. The monorail crane track 2 to be installed and maintained is placed between the baffles and fixed by the fixing bolts. The track bracket 10 is used to carry and support the pre-installed track.

[0030] This device has rotations in three directions. One is the rotation in the vertical direction between the swinging jib and the track support swinging arm 9, and the other is the rotation in the horizontal direction and the rotation in the vertical plane between the track support swinging arms 9 and the track bracket.

[0031] Specifically, a first rotating pin is provided between the swinging jib 8 and the track support swinging arm 9, and the two can rotate around the first rotating pin. A first positioning pin is provided around the first rotating pin to fix the swinging jib 8 and the track support swinging arm 9, and the circumferential surface of the formed surface in the rotation direction is the vertical plane.

[0032] The track support swinging arm 9 and the track bracket 10 are connected by a second rotating pin arranged vertically, and a second positioning pin is provided around the second rotating pin to position the horizontal rotation between the track support swinging arm 9 and the track bracket 10.

[0033] A connecting bolt arranged horizontally is provided between the track support swinging arm 9 and the track bracket 10 to fix the rotation on the vertical plane between the track support swinging arm 9 and the track bracket 10.

[0034] This device is usually used in cooperation with a pneumatic monorail crane locomotive or other types of locomotives to carry the track through the monorail crane locomotive. This device is usually connected to a power source through the monorail crane locomotive, and the monorail crane is operated to drive the track auxiliary installation and maintenance device to run on the track, and the track auxiliary installation and maintenance device is run to the track storage location.

[0035] When the track is installed in a straight line, the second positioning pin between the track support swinging arm 9 and the track bracket 10 is limited. When the track is installed with a horizontal turn, the position of the second positioning pin is changed, and a certain angle is formed between the track support swinging arm 9 and the track bracket 10 to match the track bend.

[0036] The first positioning pin between the swinging jib 8 and the track support swinging arm 9 fixes the angle between the swinging jib 8 and the track support swinging arm 9, ensuring that the track bracket places the track at a low position, docks with the existing track at a high position, and reaches the installation position.

[0037] The working principle and test steps of this device:

[0038] The operating power device lowers the track bracket to an appropriate height, lifts the pre-installed track into the bracket groove, and presses its designated end against the bracket end plate. At the same time, hexagon head bolts are used to fix the two side baffles to prevent the pre-installed track from slipping.

[0039] Operate the power device to lift the track bracket to a certain height to facilitate manual adjustment of the track during transportation and keep the track always in a horizontal state.

[0040] Lift the track to the installation position. The installer manually operates the track bracket and adjusts the track height position through the power device to connect the pre-installed track with the installed track. During this period, continuously adjust the position of the monorail hoist locomotive to ensure that there is no interference between the track and the bracket during the installation process. Finally, level the track so that it is at the same horizontal height as the previously installed track section.

[0041] When docking the tracks, hang the connection part of the installed track with the hanging chain of the hanging seat, then remove the limit bolts on the bracket, operate the power device to lower the bracket to a certain height, operate the monorail hoist locomotive to run the auxiliary track installation and maintenance device to the track storage place, and repeat the above steps to realize continuous track installation and maintenance operations.

[0042] Precautions for using this device:

[0043] (1) When the track encounters a turning situation during transportation, the limit pin shafts on the bracket hinge joint and the support arm can be removed respectively to rotate the bracket and the support arm by a certain angle so that the auxiliary installation and maintenance device can pass through the turn smoothly.

[0044] (2) When there is no turning situation during transportation, the limit pin shaft must be fixed in the middle position and firmly fixed to prevent the bracket and the support arm from rotating and swinging arbitrarily during transportation, causing injury to personnel.

[0045] (3) The running speed of the monorail hoist locomotive should not be too fast. It is best to be consistent with the walking speed of the accompanying personnel. The operator should grasp the speed control well.

[0046] (4) During transportation and installation, the installer should do a good job in protection and not touch the rotating and other parts connection parts to prevent accidental injury to personnel.
