Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and examples.
Referring to fig. 1 to 3, the full-automatic two-lining grouting trolley of the present invention includes a top form 110, side forms 120, and a trolley main frame 130.
The top formwork 110 is arranged above the trolley main frame 130, the top of the trolley main frame 130 is fixedly connected with the top formwork 110 through a steel beam 131, the steel beam 131 is preferably fixedly connected with the top formwork 110 and the trolley main frame 130 through welding, and in other embodiments, the top formwork can be fixedly connected through bolts. Preferably, the steel beams 131 are disposed at both sides above the bogie main frame 130, and the installation spaces 140 are disposed at both sides above the bogie main frame 130. As shown in FIG. 1, in order to improve the load capacity of vertical support between the top of the main frame 130 and the top formwork 110, vertical support beams 134 are vertically extended upwards from the top of the main frame 130, and the top of the vertical support beams 134 is fixedly connected with the top formwork 110.
The steel beam 131, the trolley main frame 130 and the top template 110 surround to form an installation space 140 through which a ventilation pipeline can pass; usually, installation space 140 is the door opening 141 who occupies the middle of platform truck main frame 130, but like this, door opening 141 space is less, the action of being not convenient for, in addition still need design additional bearing structure with ventilation pipe for the structure is more complicated, and the space is just littleer, and this application directly leans on the support through girder steel 131 and platform truck main frame 130, practices thrift the space, simplifies the structure, practices thrift the cost.
The peripheral profiles of the top die plate 110 and the side die plates 120 are circular arcs with the same diameter, the side die plates 120 are arranged at two side ends of the top die plate 110 and hinged with the top die plate 110, and after the trolley reaches a designated position, the side die plates 120 rotate around the hinged positions to enable the top die plate 110 and the side die plates 120 at two sides to form a large circular arc. Preferably, both the top form 110 and the side form 120 are provided with grouting ports, the grouting ports are provided with cover plates 132 capable of opening or closing the grouting ports, the cover plates 132 are hinged to one side of the grouting ports, the grouting ports can be opened or closed through hinging, and when the grouting ports are closed, the cover plates 132 can be fixedly connected with the top form 110 or the side form 120 through pins or bolts. For slip casting convenient operation, this design still includes work platform 170, work platform 170 corresponds the setting in the slip casting mouth inboard, during the slip casting, fill in the slip casting mouth with the slip casting pipeline can, work platform 170 fixes inboard at side form board 120.
Be connected with first bracing piece 151 and support cylinder 152 between side form 120 and the platform truck main frame 130, first bracing piece 151 and support cylinder 152 both ends are articulated with side form 120 and platform truck main frame 130 respectively, its length can be adjusted along its length direction to first bracing piece 151. Preferably, the lower end of the sideform 120 is provided with a hinge seat 133, and one end of the first supporting rod 151 and one end of the supporting cylinder 152 are both hinged on the hinge seat 133. Preferably, first bracing piece 151 structure is the screw jack, and first bracing piece 151 includes first lead screw and connects the connector at first lead screw both ends, and the connector at both ends is articulated with articulated seat 133 and platform truck body frame 130 respectively, the connector is connected with first lead screw spiral transmission. The fixed side template is supported well by adjusting the screw rod, so that the deformation of the fixed side template is prevented. A plurality of second support rods 150 are further distributed between the side template 120 and the trolley main frame 130 at intervals, two ends of each second support rod 150 are hinged with the side template 120 and the trolley main frame 130 respectively, and the second support rods 150 are structurally spiral screw jacks. During installation, the support cylinder 152 is operated to make the sideform 120 in place, the second support bar 150 and the first support bar 151 are adjusted to support the sideform 120, and then the hydraulic pressure of the support cylinder 152 is released.
In order to facilitate the movement of the trolley, two supporting chassis 160 arranged at intervals are arranged at the bottom of the trolley main frame 130, and the supporting chassis 160 is movably installed on the rail 180. Specifically, the support chassis 160 is provided with a jacking cylinder 162, a jacking roller 161 and a side roller 163, and each support chassis 160 is provided with two jacking cylinders which are located at two sides of the jacking roller 161 and the side roller 163. The rotation axis of the top roller 161 is horizontal, the side rollers 163 are provided with two rollers and located at two sides below the top roller 161, and the rotation axis of the side rollers 163 is vertical. The rail 180 is I-shaped, the rail 180 is embedded between the top roller 161 and the side rollers 163, the top roller 161 rolls on the surface of the rail, the side rollers 163 roll on two side surfaces of the middle vertical part of the rail 180, the left and right limiting of the supporting underframe 160 and the rail 180 is realized, and the trolley can move by the rolling of the rollers on the rail 180. When the inserted rail needs to be laid, the jacking oil cylinder 162 is opened to lift the trolley to a certain height, so that the gravity load of the trolley is on the jacking oil cylinder 162, and then the inserted rail 180 can be used for completing the laying of the rail. The trolley can be moved by pulling the trolley or pushing the trolley. In addition, due to the effect of the side rollers 163, when the rail 180 needs to be moved in the advancing direction so as to continue to advance, only the jacking oil cylinder 162 needs to be lifted, the rollers 163 on the two sides can support the rail 180, and then only the rail 180 needs to be pulled forward, so that the adjustment of the rail 180 is facilitated, the length of the rail 180 is saved, the rail 180 does not need to be paved forwards while advancing like the traditional rail 180, the rail 180 is long, and the paving alignment is troublesome.
In order to adjust the position of the trolley conveniently so that the trolley is positioned at the center of the tunnel and ensure uniform grouting thickness, the trolley main frame 130 is slidably mounted on the support underframe 160, and the trolley main frame 130 is connected with a driving mechanism 164 for driving the trolley main frame to slide; preferably, the driving mechanism 164 is a telescopic cylinder, one end of the telescopic cylinder is hinged to the support chassis 160, and the other end of the telescopic cylinder is hinged to the trolley main frame 130, so that the deformation stress caused by insufficient sliding accuracy of the trolley main frame 130 and the support chassis 160 can be avoided due to the hinge. Preferably, the upper end of the support chassis 160 is provided with a guide rail, the bottom of the trolley main frame 130 is provided with a guide groove matched with the guide rail, and the trolley main frame 130 realizes the directional movement through the cooperation of the guide rail and the guide groove, although in other embodiments, the sliding structure of the trolley main frame 130 and the support chassis 160 has many other forms. Preferably, the sliding direction of the bogie main frame 130 is perpendicular to the moving direction of the support chassis 160 along the rail 180. Thus, the main carriage 130 can move in two axes and can be adjusted in position at will.
The above embodiments are only for illustrating the technical solutions of the present invention and are not limited thereto, and any modification or equivalent replacement without departing from the spirit and scope of the present invention should be covered within the technical solutions of the present invention.
