Detailed Description
As shown in fig. 1-5, the small tunnel steel pipe combined type movable mounting system comprises two mutually parallel ground rails 1 paved outside a tunnel 15 opposite to the tunnel, rail clamping devices 2 respectively assembled on the two ground rails, 2 hydraulic jacks 3 respectively fixedly assembled on the two rail clamping devices, a conversion head 4 with one end hinged with a top rod of the jack and the other end sleeved with a steel pipe 12, at least two steel pipe supports 7 arranged at intervals and assembled on the ground rails through a sliding shoe 5 installed at the bottom, support rollers 8 capable of replacing the sliding shoe, a first hoop 6 sleeved on the steel pipe and placed on the steel pipe supports, at least two second hoops 9 sleeved on the steel pipe and provided with anti-collision rollers 10 at two sides, and a weight 11 pressed on the steel pipe. The first anchor ear 6 and the second anchor ear 9 are arranged in a staggered mode. The two hydraulic jacks 3 are respectively connected with a hydraulic pump station 13 through oil pipes 14.
As shown in fig. 6, 7 and 8, the conversion head 4 includes two small end plates 4b facing the hydraulic jack, one large end plate 4d facing the steel pipe end, a connecting frame 4c connecting the two small end plates and the large end plate into a whole, a pair of ear plates 4a with hinge holes respectively welded on the outer end face of each small end plate, a sleeve 4e welded on the outer end face of the large end plate and capable of being inserted into the end of the steel pipe, and a positioning clamping groove 4f arranged at the top of the sleeve. Each pair of paired ear plates 4a is hinged with the ejector rod of one hydraulic jack through a hinge shaft. The sleeve can be inserted on the steel pipe 12, the pipeline port is welded with a positioning ring 10a, and the positioning ring 10a is clamped into a positioning clamping groove 4f at the top of the sleeve for positioning.
The steel pipe support 7 is a support with a semicircular groove on the top surface, the bottom of the support is a bottom plate which spans across two ground rails, and two sliding shoes 5 which can be assembled on the ground rails are arranged on the bottom surface of the bottom plate through connecting bolts.
The weight 11 is a cuboid with a semicircular arch groove at the bottom, and straddles the steel pipe, and the semicircular arch groove is clamped on the top surface of the steel pipe. The weight 11 is a concrete block.
The first hoop 6 is formed by connecting an upper half hoop and a lower half hoop through bolts and is clamped on the steel pipe. The second hoop 9 is formed by connecting left and right semi-circular hoops through bolts and is clamped on the steel pipe. And anti-collision rollers 10 are arranged on two sides of the second anchor ear to prevent the steel pipe from deflecting and rubbing against the tunnel after entering the small tunnel.
When the steel pipe combination moving in the small tunnel is carried out by adopting the invention, as shown in figure 1, steel pipe welding and corrosion prevention operation is carried out outside the tunnel 15, two steel pipe supports 7 are arranged on a ground rail 1 through sliding shoes 5 at the bottom, two first anchor hoops 6 are sleeved on a steel pipe 12 at intervals, and the positions of the steel pipe sleeved with the first anchor hoops are arranged on the steel pipe supports; the rail clamping device 2 is slid to drive the hydraulic jack 3 and the conversion head 4 to move towards the steel pipe, a sleeve 4e of the conversion head is sleeved into the end head of the steel pipe, a positioning clamping groove 4f of the sleeve is positioned at the top, a positioning ring 10a is inserted into the positioning clamping groove 4f to prevent the sleeve and the steel pipe from rotating, and meanwhile, in order to prevent the hydraulic jack 3 from driving the sleeve to fall off when the ejector rod is recovered, local welding is adopted between the positioning ring 10a and the positioning clamping groove 4 f; the weight 11 is then pressed against the steel pipe. And then, starting the hydraulic pump station 13, driving the ejector rod of the hydraulic jack 3 to eject out to generate ejection force, transmitting the ejection force to the conversion head 4, uniformly transmitting the ejection force to the steel pipe by the conversion head, and forward pushing the steel pipe towards the tunnel direction, wherein the sliding shoe 5 at the bottom of the steel pipe support 7 stably slides forward along the ground rail 1. When the sliding shoe slides to approach the tunnel and leave the ground rail, the sliding shoe is taken down and changed into the support roller 8, the support roller 8 moves forward along the ground, and the sliding shoe continues to move forward by virtue of the pushing force until the sliding shoe moves to the installation position. In the process that the steel pipe is pushed forward, the upward pushing component force is counteracted by the weight block 11, so that the steel pipe is prevented from tilting, and the steel pipe is ensured to stably move in a horizontal state. After the steel pipe enters the tunnel, the anti-collision rollers 10 on the two sides of the second anchor ear can prevent the steel pipe from deflecting and rubbing against the tunnel after entering the small tunnel.
After the steel pipe moves to the installation position in the tunnel, as shown in fig. 9, a group of jacks 16 is adopted to jack up the steel pipe, and the first anchor ear, the second anchor ear, the steel pipe support and the support roller are removed.
