DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0028] With reference to Figures 1-5 For an embodiment of the utility model, a rail trolley for cleaning a shield door is disclosed, specifically the rail trolley comprises a guide rail unit 1 and a vehicle body 2 walking on the guide rail unit 1, wherein the guide rail unit 1 comprises a frame 11 and two guide rails mounted on the frame 11, of course, in order to adjust the levelness of the whole frame 11, a ground anchor can also be threadedly connected to each corner of the bottom of the frame 11;

[0029] In addition, the vehicle body 2 comprises a chassis and four rail wheels mounted below the chassis, the rail wheels rotate above the guide rails to maintain straight movement, the rail wheels can be manually pushed to rotate, or a hub motor can be built-in to drive electrically, and the hub motor driven wheel rotation is a conventional means for the person skilled in the art, which will not be described in detail here.

[0030] A lifting assembly 3 is arranged above the vehicle body 2, and a water spraying assembly 4 is mounted at the front end of the lifting assembly 3; wherein a positioning assembly 5 is further arranged on the guide rail unit 1, and adjacent two guide rail units 1 are connected through a buckling assembly 6, specifically the guide rail units 1 can be assembled between each other, and adaptive assembly can be carried out according to the width of the shield door to be cleaned, so as to meet the applicability of use, and the modular design is convenient for disassembly and transportation, and also improves the convenience of storage.

[0031] In some embodiments, the lifting assembly 3 in the utility model comprises two guide rods 31 fixedly mounted above the vehicle body 2 and a screw piece 32 rotatably connected to the vehicle body 2.

[0032] The load seat 33 is threadedly connected with the screw rod 32, and a motor 34 is fixedly installed on the bottom of the vehicle body 2, and the shaft end of the motor 34 is fixedly connected with the screw rod 32.

[0033] Further, the water spraying assembly 4 in the embodiment comprises a support pipe 41 fixed on the load seat 33, a hollow pipe 42 is fixed on the front end of the support pipe 41, a spray head is connected with the front end of the hollow pipe 42, and the hollow pipe 42 is connected with a water supply assembly through a hose.

[0034] That is to say, in the actual operation process, the motor 34 can drive the screw rod 32 to rotate, and since the screw rod 32 is threadedly connected with the load seat 33, the load seat 33 can be driven to linearly slide between the two guide rods 31, so that the height adjustment is realized.

[0035] Of course, since the hollow pipe 42 is fixed on the load seat 33 through the support pipe 41, the hollow pipe 42 can drive the spray head to spray and flush at different heights in the state that the load seat 33 moves up and down, so that the cleaning process of the shielding door at different heights is met. Of course, the above operation is only for cleaning at one height range, when the width position of the spray and flushing needs to be changed, the vehicle body 2 can be linearly moved on the guide rail unit 1 by pushing, so that the shielding door can be cleaned at multiple positions. Since the vehicle body 2 is linearly moved under the restriction of the guide rail unit 1, the distance between the spray head and the shielding door is fixed, so that the cleaning stability of the shielding door is effectively ensured.

[0036] In some embodiments, the positioning assembly 5 in the utility model comprises two rod members 51 inserted into the frame 11 of the guide rail unit 1, and the rod members 51 are provided with scale portions 52 on the outer sides.

[0037] The lock bolt 53 is threadedly connected with the frame 11, and the bottom end of the lock bolt 53 abuts against the outer side of the rod member 51.

[0038] That is, in the actual installation of the guide rail unit 1, in order to ensure that the two ends of the guide rail unit 1 and the door frame of the whole shielding door are kept horizontal, to avoid the problem of the straight movement of the vehicle body 2 and the inclination of the shielding door, in the embodiment, two pullable rod members 51 are used, the two rod members 51 on both sides are pulled out during use, the position is measured through the scale part 52, the distance between the two ends of the whole frame 11 is kept consistent with the door frame of the shielding door, so that the horizontal movement between the vehicle body 2 and the shielding door can be ensured, after the adjustment is completed, the position locking of the rod member 51 can be completed by rotating the locking bolt 53.

[0039] In some embodiments, the buckle assembly 6 in the utility model comprises a T-shaped rod 61 inserted between the two guide rail unit 1 frames 11, the end outer side of the T-shaped rod 61 is embedded with a positioning glass bead 62, the ladder platform of the T-shaped rod 61 and the positioning glass bead 62 are located on both sides of the two frames 11, and specifically, the positioning glass bead 62 is a prior art, the telescopic part of which protrudes outward of the T-shaped rod 61 and stops the inner side of the frame 11.

[0040] On the basis of the above-mentioned embodiment, the middle part of the T-shaped rod 61 in the embodiment has a step part 611 and an inner shrink part 612, the diameter of the inner shrink part 612 is smaller than that of the step part 611, and the two frames 11 are penetrated by the inner shrink part 612.

[0041] The outer side of the inner shrink part 612 is slidably connected with a gasket 613, the gasket 613 is stopped on the outer side of the frame 11, and a spring 614 is arranged between the T-shaped rod 61 and the gasket 613.

[0042] The purpose of the spring 614 and the gasket 613 is to facilitate the disassembly of the whole T-shaped rod 61, when the two guide rail units 1 need to be separated, the positioning glass bead 62 on the T-shaped rod 61 can be pressed to make the telescopic end shrink, at this time, under the pushing of the spring 614, the whole T-shaped rod 61 moves outward, so that the disassembly is completed, and vice versa, the T-shaped rod 61 is inserted between the two frames 11, when the gasket 613 abuts against one frame 11 and the positioning glass bead 62 is stopped on the side edge of the other frame 11, the connection work is completed.

[0043] In summary, in the utility model, the vehicle body 2 is moved on the guide rail unit 1, so as to ensure the straight movement of the vehicle body 2 and avoid the deviation of the vehicle body 2 during pushing and pulling, thereby avoiding the problem of the inclination of spraying, in addition, the positioning assembly 5 is arranged on the guide rail unit 1, after the positioning assembly 5 is positioned with the door frame of the shielding door, the two ends of the guide rail unit 1 and the door frame of the whole shielding door are kept horizontal, the horizontal movement between the vehicle body 2 and the shielding door is ensured, and the problem of water spraying is improved.
