They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention. The terms "connected" and "connection" used in the present invention should be understood in a broad sense. For example, they can be fixed connections or detachable connections; they can be directly connected or indirectly connected through intermediate components. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0031] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0032] like Figures 1 to 4 As shown, a simple movable trolley for use in tunnel cable troughs and lining tubes comprises a top frame 1, a first leg 2 and a second leg 3;

[0033] The top of the top frame 1 is covered with a top plate 9, and the top frame 1 includes a first long side and a second long side that are arranged oppositely;

[0034] The first leg 2 is fixed to the first long side of the top frame 1, and there are at least two first legs 2 arranged at intervals; the lower end of the first leg 2 is equipped with a walking wheel 7 that can be placed in the cable trough 100;

[0035] The second leg 3 is fixed to the second long side of the top frame 1, and there are at least two second legs 3 arranged at intervals; the lower end of the second leg 3 is equipped with a climbing wheel 8 that can walk along the lining; the length of the second leg 3 is shorter than that of the first leg 2;

[0036] The walking wheel 7 and the wall climbing wheel 8 are both brake universal wheels;

[0037] When the simple movable trolley for the cable trough and lining of the tunnel moves, the personnel push it along the tunnel route; when the simple movable trolley for the cable trough and lining of the tunnel is in working state, the position of the movable trolley remains stationary, the universal wheels are locked, and the upper surface of the top plate 9 is horizontal, so that the personnel can stand firmly;

[0038] The top frame 1 and the legs can be made of channel steel, square steel tube or angle steel. The size and width of the top frame 1 and the height of the first leg 2 and the second leg 3 depend on the size and line shape of the specific cable trough and lining.

[0039] The top frame 1 can be made of full angle steel or four-sided angle steel with intermediate steel bars, and then bamboo plywood is used as the top plate 9, which is punched with holes, and the bamboo plywood is tied or bolted to the top surface frame.

[0040] Further, such as Figures 1 to 4 As shown, a first reinforcing rod 4 is vertically fixed between the first leg 2 and the adjacent second leg 3, and a second reinforcing rod 5 connected to the top frame 1 is fixed on the first reinforcing rod 4; a third reinforcing rod 6 is vertically fixed between two adjacent first legs 2, and the third reinforcing rod 6 is one or more; a reinforcing triangle plate or a fourth reinforcing rod 11 is fixed between the second leg 3 and the bottom of the top frame 1; these reinforcing rods are used to strengthen and stabilize the main structure of the mobile trolley of the utility model.

[0041] Further, such as Figure 3 to Figure 4 As shown, the lower edge of the second long side of the top frame 1 is wrapped with a corner protection strip 10. The corner protection strip 10 is made of a material with a thickness of more than 2 mm, and the second long side of the top frame can be soft-wrapped, such as silicone, foam, rubber, latex, EVA, etc.; the corner protection strip 10 is close to the inner surface of the lining but does not contact it under normal conditions, and there is a spacing of less than 10 cm; if the wall-climbing wheel 8 slips and tilts downward, the corner protection strip 10 moves down with the top frame 1 and rests on the inner surface of the lining, and the friction force can be used to prevent the top platform from continuing to fall downward.

[0042] Furthermore, in order to facilitate the adaptation to the inner surface of the curved lining, the surface of the wall climbing wheel 8 is polished to adapt to the inner surface of the lining at the walking position to increase the contact area with the inner surface of the lining, or Figure 4 As shown in , the wall-climbing wheel 8 is a spherical universal wheel, and the wall-climbing wheel 8 is made of materials such as rubber wheel, nylon, polyurethane, etc.

[0043] Further, such as Figures 2 to 4 As shown, at least two wall-climbing wheels 8 are fixed to the lower end of one of the second legs 3 ; the wall-climbing wheels 8 are arranged in one or more rows along the length direction of the top frame 1 .

[0044] Further, such as Figures 2 to 4 As shown, the wall-climbing wheels 8 on one of the second legs 3 are arranged in one or more rows along the width direction of the top frame 1. When the simple movable trolley for tunnel cable troughs and lining tubes is in working condition, each of the wall-climbing wheels 8 is in contact with the lining.

[0045] In a specific example, Figures 2 to 4 As shown, the wall-climbing wheel 8 includes a first wall wheel 81 and a second wall wheel 82 which are arranged at intervals along the width direction of the top frame 1; a support plate 31 is horizontally arranged at the lower end of the second leg 3, the first wall wheel 81 is fixed to the bottom surface of the support plate 31, the second wall wheel 82 is located lower than the first wall wheel 81, and the second wall wheel 82 is fixed to the bottom surface of the support plate 31 through an extension leg 32. The length of the first leg 2 and the extension leg 32 is customized according to the position between the top frame 1 and the inner surface of the lining, or the length of the extension leg 32 is adjustable; the adjustable extension leg can adopt a threaded sleeve telescopic structure. When making this mobile trolley, first customize the first leg 2 so that the first wall wheel 81 walks along the surface of the lining; then adjust the length of the extension leg so that the second wall wheel 82 contacts the inner surface of the lining.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
