Detailed Description

Referring to the figure 1, for the utility model discloses a shield constructs construction track and demolishs and use transport vechicle, dead lever 1 including a pair of parallel to each other and level setting, the rigid coupling is at dead lever 1 upper surface and the vertical bracing piece 2 that upwards extends respectively, and the crossbeam 3 of rigid coupling between two bracing pieces 2, distance between two dead levers 1 is greater than the distance of track or section of track, install the chain block 4 that is used for hoisting track or section of track on the crossbeam 3, it can adopt chain block or electric block, indicate with electric block in the picture, be supporting facility between this chain block 4 and the transport vechicle, consequently, need not the dismouting around using, because frequent dismouting among the prior art has been solved, and lead to the problem that the bolt takes place not hard up or the section of jurisdiction warp between the adjacent section of jurisdiction. The crossbeam 3 is less than the top in tunnel, and hoist and mount in-process hoist and mount 4 can not touch the top in tunnel.

In order to improve the stability of the transport vehicle and the bearing capacity of the support rods 2, the two sides of each support rod 2 are respectively provided with an auxiliary support rod 5, one end of each auxiliary support rod 5 is fixedly connected with the side wall of each support rod 2, the other end of each auxiliary support rod is fixedly connected with the upper surface of the fixed rod 1, and the two auxiliary support rods 5 are symmetrically arranged.

Every dead lever 1 keeps away from one side of bracing piece 2 and all welded fastening has a pair of platelike crossbearers 11, it is mutually perpendicular between crossbearers 11 and the dead lever 1, use bracing piece 2 to set up as central symmetry between two crossbearers 11, the center department of keeping away from dead lever 1 one side at crossbearers 11 is equipped with a set of removal subassembly 6, removal subassembly 6 includes threaded connection at crossbearer 11 center department and vertical downwardly extending's connecting rod 61, the spheroid 62 of crossbearer 11 one end is kept away from at connecting rod 61 to the rigid coupling, with connecting rod 61 through spheroid 62 ball hinge joint connected's support 63, and install and keep away from the walking wheel 64 of spheroid 62 one side at support 63, because be dismantling fixed connection between removal subassembly 6 and the crossbearers 11, consequently as required, the staff can change or overhaul removal subassembly 6.

The track or the track panel is detached and then bound by using a rope, during transportation, the transport vehicle is moved to the two sides of the track or the track panel, the bound track or the track panel is hoisted by the hoist 4 and lifted to a certain height, then the transport vehicle is pushed to move towards the direction of the transport means, and when the hoisted track or the track panel moves to the upper side of the transport means, the track or the track panel is detached.

Because walking wheel 64 is connected with crossbearer 11 through ball articulated mode, consequently it can adapt to the tunnel of different diameters, and application scope is wider, and at the in-process that removes, no matter whether the transport vechicle climbs towards one side in the tunnel (the tunnel inner wall after the shield construction is the cambered surface), walking wheel 64 homoenergetic rotates the adjustment according to the radian self-adaptation of tunnel inner wall, makes walking wheel 64's wheel face fully contact with the tunnel inner wall all the time, has improved the reliability in the transportation.

For preventing that removal subassembly 6 from leading to the transport vechicle to take place to empty towards opposite side slope when climbing, cause the potential safety hazard, keep away from one side of dead lever 1 at crossbearer 11 and set up two sets of auxiliary stay subassemblies 7 for carry out auxiliary stay to the transport vechicle, guarantee the stability of transport vechicle in the transportation.

The two auxiliary supporting components 7 are in a splayed shape and are symmetrically arranged by taking the moving component 6 as a center. The auxiliary supporting assembly 7 comprises a sleeve 71 fixedly connected to the lower surface of the cross frame 11, the lower end of the sleeve 71 is obliquely arranged towards one side far away from the moving assembly 6, an expansion rod 72 which is inserted in the sleeve 71 in a sliding mode, one end of the expansion rod extends out of the sleeve 71, a spring 73 connected between the sleeve 71 and the expansion rod 72, and a bull's eye wheel 74 horizontally arranged at one end, far away from the cross frame 11, of the expansion rod 72, and when the transport vehicle is in a ground-off state, the height of the bull's eye wheel 74 is 4-6cm lower than; when the telescopic rod 72 is completely retracted into the sleeve 71, the height of the bull-eye wheel 74 is 4-6cm higher than that of the walking wheel 64.

The inner wall of the sleeve 71 far away from one end of the cross frame 11 and the outer wall of the telescopic rod 72 near one end of the cross frame 11 are fixedly connected with limit rings 75 for limiting the telescopic rod 72 and preventing the telescopic rod from being separated from the sleeve 71.

When the transport vehicle climbs towards one side, part of the rod body of the telescopic rod 72 close to the uphill side is stressed and retracted into the sleeve 71, so that the bull's eye wheel 74 is supported on the inner wall of the tunnel, the telescopic rod 72 close to the downhill side extends out of the sleeve 71 under the influence of the restoring force of the spring 73, the bull's eye wheel 74 is supported on the inner wall of the tunnel, and the auxiliary support for the transport vehicle is realized; meanwhile, when the transport vehicle runs downhill, the auxiliary supporting component 7 can also play a role in shock absorption and buffering, and the stability of the transport vehicle is further improved.

In the transportation, the track or the section of track of being hoisted can sway indefinitely under the dual function of inertial force and gravity, and then lead to the automobile body to take place to rock, when serious, probably can make the automobile body take place to turn on one's side, cause the potential safety hazard, for solving above-mentioned technical problem, set up respectively in two relative one sides of bracing piece 2 and carry out fixed locating component 8 to the track or the section of track of hoist, after the hoist and mount is accomplished, it is fixed to track or section of track through two locating component 8, prevent that it from taking place to rock at the in-process of transportation.

The positioning assembly 8 comprises a pull rope 81 which penetrates through the support rod 2 in a sliding mode, a hook 82 which is fixedly connected to the pull rope 81 and is close to one end of a hoist 4, and a pull ring 83 which is fixedly connected to the pull rope 81 and is far away from one end of the hook 82, the pull rope 81 penetrates through the support rod 2 in the direction of the length of the cross beam 3, a plurality of threaded holes 21 are formed in the support rod 2 in the vertical equidistance of one side, which is close to the pull ring 83, of the support rod, the threaded holes 21 are internally connected with a T-shaped rod 9, and.

When the fixing is carried out, the hook 82 of the positioning component 8 at one side is hooked on a rope binding a track or a track panel, then the pull ring 83 is pulled downwards, when the pull rope 81 is in a tensioning state, the T-shaped rod 9 penetrates through the pull ring 83 and is in threaded connection with the corresponding threaded hole 21, so that the fixing of the pull rope 81 is realized, then the operation is repeated, and the hook 82 at the other side is hooked on the rope and is fixed.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
