[0025] In response to the above problems, an embodiment of the present application provides a walking automatic maintenance trolley. The technical solution of the embodiment of the present application is described in detail below with reference to the accompanying drawings.
[0026] like Figure 1 and Figure 2The walking automatic maintenance trolley shown includes an automatic maintenance system and a walking system. The automatic maintenance system is mounted on the walking system, which drives the entire device to move while automatically maintaining the tunnel's inner wall. The key points of this application lie in the walking system, which includes a gantry 1 configured as a portal frame on a YZ plane. Depending on the specific stability requirements, a connecting reinforcement column can be provided between the gantry's column and the transverse connecting beam. Multiple gantry 1s are provided and fastened together by crossbeams 2 to form a portal-shaped frame when viewed from the YZ plane. The walking system of this application also includes crossbeams 2, each side of which has through-holes. The walking system of this application also includes a support frame 3, which is a portal-shaped frame when viewed from both a YZ plane and an XY plane. The walking system of this application also includes a limit frame 4 configured as a portal-shaped fork frame. The walking system of this application also includes rails 5, a forward hydraulic telescopic cylinder 6, a vertical hydraulic telescopic cylinder 7, and a roller frame 8.
[0027] In this application, the crossbeam 2 is fixedly arranged at the bottom of the door frame 1 to fix multiple door frames 1 together, the support frame 3 is fixedly arranged on the inner side of the through holes at both ends of the crossbeam 2 to support the entire equipment, and the upper end of the limit frame 4 is fixedly arranged in the middle of the crossbeam 2.
[0028] The telescopic end of the hydraulic telescopic cylinder 7 that moves up and down passes through the konghou of the crossbeam 2 and is connected to the bottom or one side of the door frame 1 through a flange plate, etc., and a roller frame 8 is set under the cylinder body of the hydraulic telescopic cylinder 7 that moves up and down through a flange plate, etc., and a roller is connected to the roller frame 8 so that the roller rotates on the roller frame 8. A hanger 11 is fixedly connected to one side of the roller frame 8, and the hanger 11 is connected to the track 5 so that the track 5 is located in the door fork of the limit frame 4, and at the same time, the track 5 is located in the door frame below the support frame 3; the roller frame 8 moves up and down with the telescopic work of the hydraulic telescopic cylinder 7 that moves up and down, so that the hanger 11 carries the track 5; one end of the track 5 is connected to the forward hydraulic telescopic cylinder 6, and the other end of the forward hydraulic telescopic cylinder 6 is connected to the roller frame 8 on one side.
[0029] In this way, the present application sets up a door-shaped support frame 3 so that the entire gantry 1 falls to the ground to support the entire device when the hydraulic telescopic cylinder 7 is retracted. Since the main support of the entire device is on the support frame 3, and the hanger 11 carries the track 5 off the ground, at this time, the track 5 is driven to move in the X direction by the extension and contraction of the forward hydraulic telescopic cylinder 6, and the limit frame 4 plays a role in positioning and limiting. After the track 5 moves a certain distance, the hydraulic telescopic cylinder 7 that moves up and down is activated again, so that the hanger 11 on the roller frame 8 carries the rollers and the track 5 to contact the ground and lift the entire gantry 1 so that the support frame 3 leaves the ground. At this time, the entire device is mainly supported by the contact and cooperation between the roller frame 8 and the track 5. At the same time, the forward hydraulic telescopic cylinder 6 is activated again, pulling the entire gantry 1 to move on the track 5, thereby realizing the displacement of the gantry 1.
[0030] During the entire process, the forward hydraulic telescopic cylinder 6 is used as the power for movement to pull the entire equipment to move on the track 5. At the same time, the forward hydraulic telescopic cylinder 6 drives the track 5 to change its path, so that the movement of the entire equipment is changed from the previous movement method by rolling rollers on a fixed track to a walking-type movement method in which the entire equipment is pulled to move by moving the hydraulic telescopic rod. When moving, the power output of the equipment is the forward hydraulic telescopic cylinder 6, and when stopping, the support frame 3 is placed in contact with the ground to stop, avoiding traditional brakes, so that the entire equipment can ensure safe walking on a slope with a maximum gradient of 11%, and there will be no slipping when working on a construction site with a certain slope. Moreover, the entire movement is smooth and stable to ensure safety.
[0031] In one embodiment, Figure 2 As shown, a gap is provided between the bottom of the limit frame 4 and the track 5. Both ends of the forward hydraulic telescopic cylinder 6 rotate in the XY plane about the Z axis, restricting the track 5 to movement in the X direction during the telescopic movement of the forward hydraulic telescopic cylinder 6. The limit frame 4 is provided to limit the lateral deformation of the track 5 during subsequent steering.
[0032] In one embodiment, a roller frame 8 is slidably connected to the bottom of a vertically movable hydraulic telescopic cylinder 7 using a slide rail, with a certain gap left at the connection point of the slide rail. A lateral hydraulic cylinder 9 is fixedly connected to the bottom of the vertically movable hydraulic telescopic cylinder 7 on the front side. The telescopic end of the lateral hydraulic cylinder 9 is connected to the roller frame 8 via a connector, allowing the roller frame 8 to move slightly in the Z direction. In this application, the actual movement of the roller frame 8 is very small. The lateral movement of the roller frame 8 drives one end of the track 5 to move. Since the entire track 5 is a long track, the lateral movement of the roller frame 8 causes the entire track 5 to deform from the rear end to the front end. The lateral movement of the front end does not exceed 10 cm. A limiter 4 is also provided at the middle position to prevent excessive deformation of the rear end. This allows the entire device to achieve slight steering of the front end through deformation of the front end of the track 5 without requiring rotation of the rear end in the case of a non-precise fit.
[0033] In one embodiment, the track 5 is an I-rail, and the roller is a groove wheel that is compatible with the I-rail. The I-rail is embedded in the groove wheel. It should be noted that there is a gap between the I-rail and the groove edge of the groove wheel. The gap is extremely small. The hanger 11 is a U-shaped frame. Rollers are provided at both ends of the bottom of the hanger 11 to abut the lower side of the bottom track of the track 5. In this way, the entire roller frame 8 can smoothly allow the roller to roll on the track 5 while driving the track 5 laterally when the hydraulic telescopic cylinder 7 is moved up and down to lift the track 5. The above-mentioned gap is based on the roller moving laterally relative to the track 5 while the roller on the hanger is still on the lower side of the track 5.
[0034] In one embodiment, one end of the crossbeam 2 is detachably connected to an inclined support 10 , and one end of the inclined support 10 is in contact with the ground to provide auxiliary support when the equipment is parked.
[0035] Finally, it should be noted that, in this document, relationships such as first and second, etc., are used solely to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms include, comprise, or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
