Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

Fig. 3-7 show a tool for installing rims at two sides of a pedal according to the present invention, which comprises a bracket 4, a working table 41 installed on the bracket 1, and two sets of installation units. The two sets of units are arranged above the worktable 41 in a left-right opposite manner. The mounting unit comprises a swivel arm 5, a drive assembly 7 and a pressure plate 6. The rotating arm 5 is arranged above the working platform 41 and is connected with the bracket 4 in a vertical rotating way. Specifically, a cross shaft is mounted on the bracket 4, and the middle parts of the rotating arms 5 on both sides are sleeved on the cross shaft through holes, so that the rotating arms 5 can rotate up and down around the cross shaft. In order to reduce wear between the swivel arm 5 and the transverse shaft, a bushing is also mounted between the swivel arm 5 and the transverse shaft. A driving assembly 7 is connected to the boom 5 for driving the boom 5 to rotate up and down. The drive assembly 7 is preferably a pneumatic cylinder. The first end of the cylinder is hinged with the rotating arm 5, and the second end of the cylinder is hinged with the bracket 4. The pressing plate 6 is installed at one end position on the rotating arm 4, and the middle portion of the pressing plate 6 is hinged to the rotating arm 4 so that the pressing plate 6 can rotate about the hinged position. Through the above structure design, under the driving of the driving assembly 7, one end of the rotating arm 5 can move downwards, and then the pressing plate 6 at the end is driven to move downwards, so as to be close to the working table 41.

The bottom surface of the pressing plate 6 is provided with a first tooth groove 61 corresponding to at least part of the teeth on the pedal 1 and a second tooth groove 62 corresponding to at least part of the teeth on the frame 11. The first tooth grooves 61 and the second tooth grooves 62 are arranged in parallel and each extend in a first direction (the first direction is the longitudinal direction of the platen 6). When the frame 11 is fitted to a predetermined position on one side of the step panel 1, there is a positioning state between the pressure plate 5 and the step panel 1 and between the pressure plate 5 and the frame 11. In the positioning state, the first tooth slot 61 is engaged with at least a part of the teeth on the pedal 1, and the second tooth slot 62 is engaged with at least a part of the teeth on the rim 11. The number of the first tooth grooves 61 and the second tooth grooves 62 is determined according to actual needs. Through the structure design, when the frame 11 is located the preset position of one side of the pedal 1, the pressing plate 5 stretches across the frame 11 and the bracket of the pedal 1, the first tooth groove 61 is mutually limited with the pedal 1, the second tooth groove 62 is mutually limited with the frame 11, so that the pressing plate 5 can synchronously limit the pedal 1 and the frame 11, the assembly gap between the pedal 1 and the frame 11 is always controlled at the set standard value, and large fluctuation can not occur.

The tool of the present embodiment includes a fixing device for fixing the pedal 1 on the work table 41. The fixture comprises a first upright 8 and a second upright 9 mounted on a work surface 41. The first upright column 8 and the second upright column 9 are both positioned at two sides of the working table 41, and the first upright columns 8 at two sides are provided with positioning shafts 81. The positioning shaft 81 extends in the horizontal direction. The top surfaces of the second upright posts 9 on both sides are processed with positioning shaft holes 91. As known from the background art, a triangular bracket 2 is installed below the pedal 1. The triangular support 2 is provided with a main wheel axle hole 21 matched with the positioning axle 81 and an auxiliary wheel axle 22 matched with the positioning axle hole 91. When the stair of the escalator is positioned, the main wheel shaft hole 21 on the triangular support 2 is clamped on the positioning shaft 81, the auxiliary wheel shaft 22 on the triangular support 2 is clamped on the positioning shaft hole 91, and the positioning shaft 81 is provided with a step, so that the left and right limiting functions of the triangular support 2 are achieved. Through the positioning mode, the positioning of the triangular support 2 is realized, and the positioning of the pedal 1 is further realized. In this embodiment, when the tripod 2 is placed on the positioning device, the pedal 1 is in a horizontal state.

In order to facilitate the installation of the screws between the frame 11 and the triangular support 2, an escape notch 64 is formed on one side of the pressure plate 5. The screw installation work can extend into the lower part of the pressure plate 6 through the avoiding notch 64 so as to facilitate the screw screwing work.

As shown in fig. 6, both ends of the pressing plate 6 in the first direction are mounted with shielding plates 63. The first end of the protection plate 63 is fixedly connected with the pressing plate 5, and the second end extends to one side far away from the pressing plate 5 along the first direction. The protection plate 63 can prevent the body of an operator from extending into the interior of all the tools, and the safety of the assembling process is improved.

During specific assembly, as shown in fig. 8, the main axle hole 21 on the triangular bracket 2 is clamped on the positioning shaft 81, and the auxiliary axle 22 on the triangular bracket 2 is clamped on the positioning shaft hole 91, so that the pedal 1 is fixed. The rims 11 are placed at approximate positions on both sides of the pedal 1. The rotating arm 4 is driven to rotate by the driving assembly 7, so that the two side pressing plates 6 move downwards. The position of the frame 11 is finely adjusted so that when the pressing plate 6 moves downward, the first tooth grooves 61 on the pressing plate 6 are matched with the corresponding position tooth parts on the pedal 1, and the second tooth grooves 62 on the pressing plate 6 are matched with the corresponding position tooth parts on the frame 1. Under the compression of the pressing plate 6, the frames 11 on the two sides and the pedal 1 are mutually limited, and finally, screws with corresponding quantity are screwed in to fix the frames 11.

Through the assembly of the tool of the embodiment, the gap between the frame 11 and the pedal 1 is controlled within a preset numerical range, the size consistency of the assembled step is good, the assembly precision of the frame is effectively improved, and the assembly requirement of the escalator step is met.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all utilize the equivalent structure or equivalent flow transformation that the content of the specification does, or directly or indirectly use in other related technical fields, all including in the same way the patent protection scope of the present invention.
