In theory, the conveying track can adopt a single track or multiple tracks, but in order to achieve the simplicity and safety of the structure, the movable track 3 and the fixed track 2 are both double tracks comprising two side tracks; the track changing mechanism can adopt sliding type, push-pull type and the like, so long as the movable track 3 and the fixed track 2 can be ensured to be aligned accurately, and the space can be reserved. However, if it is desired to achieve these two points, the movable rail 3 is always in a parallel state during the track changing process, and in order to achieve this object, as shown in fig. 2, the track changing mechanism is a swing arm 4, one end of the swing arm 4 is hinged on the movable rail 3, the other end is hinged on the rail supporting structure 1, at least two swing arms 4 are connected on the movable rail 3 on one side, and the swing arms 4 on the same side are equal in length and parallel to each other. Usually, each side of the movable rail 3 adopts two swing arms 4, the movable rail 3 and the rail supporting structure 1 form a parallelogram structure, the hinge points of the two swing arms 4 on the rail supporting structure 1 are fixed, and then the movable rail 3 is always parallel to a connecting line between the two hinge points in the track changing process, so that the movable rail 3 can be accurately in parallel butt joint with the fixed rail 2 as long as the connecting line of the two hinge points is parallel to the fixed rail 2 in the installation process.
After the rail butt joint is finished, the movable rail 3 can be locked, so that the safety is improved, a locking mechanism is required to be arranged for the movable rail 3, the locking mechanism can be in the modes of common bolt locking, bolt locking and the like, and particularly when a swing arm 4 is adopted as a rail changing mechanism, as shown in fig. 3, the locking mechanism comprises a bolt seat 51 and a locking bolt 52, the bolt seat 51 is arranged on the movable rail 3 corresponding to the swing arm 4, a bolt hole is arranged on the bolt seat 51, and the distance between the bolt hole and the movable rail 3 is equal to the width of the swing arm 4;
when the movable rail 3 is in butt joint with the fixed rail 2, the swing arm 4 is attached to the movable rail 3, and the locking bolt 52 is inserted into the bolt hole to lock the swing arm 4. The swing arm 4 is attached to the movable rail 3, so that the movable rail 3 cannot move inwards any more, and simultaneously, the swing arm cannot move outwards any more by utilizing the locking bolt 52, both sides of the movable rail 3 are fixed, and the movable rail 3 is locked. In addition, for accurate butt joint, the butt joint of the movable rail 3 and the fixed rail 2 can be arranged on an inclined plane, and meanwhile, a bolt is additionally arranged at the butt joint for locking.
The movable rail 3 can be completely driven by manual operation or by being matched with equipment such as a hydraulic cylinder, an air cylinder, an electric push rod and the like, and the swing arm 4 is adopted as a rail changing mechanism, so that the actual movable rail 3 moves obliquely and parallelly in the rail changing process, the driving effect of the rod-shaped telescopic driving piece is not ideal directly, and the movable rail 3 is difficult to be driven stably directly for traction equipment adopting a winch. In view of this problem, the present invention proposes two driving modes, namely, converting the oblique motion into the linear motion and then driving, so as to solve the above-mentioned problems well.
In a first mode, as shown in fig. 4, the track supporting structure 1 includes a supporting beam 11, the movable track 3 is disposed on the supporting beam 11, sliding blocks 71 are respectively disposed on the supporting beam 11 and corresponding to the movable tracks 3 on two sides, the sliding blocks 71 are slidably connected with the supporting beam 11, clamping rollers 72 are disposed on two sides of a top of the sliding blocks 71, roller shafts of the clamping rollers 72 are vertically disposed, the clamping rollers 72 have annular steps, and the movable track 3 is erected on the annular steps and is clamped between the clamping rollers 72 on two sides of the sliding blocks 71. The sliding block 71 moves linearly along the supporting beam 11 during the track changing process, and the clamped movable rail 3 can slide axially relative to the sliding block 71 due to the clamping roller 72. The movable rail 3 clamped on the movable rail 3 can move obliquely by driving the sliding block 71 to move along the supporting beam 11, so that the oblique movement of the movable rail 3 is converted into the linear movement of the sliding block 71, and the movable rail 3 is driven to change rails by using the driving mechanism.
In addition to the first mode, as shown in fig. 5, the present invention further provides a second mode, a transverse guide rod 12 is provided on the track supporting structure 1, sliding blocks 71 are respectively provided on the transverse guide rod 12 corresponding to the movable tracks 3 on both sides, the sliding blocks 71 are slidably connected with the transverse guide rod 12, a connecting rod 73 is provided between the sliding blocks 71 and the corresponding movable tracks 3, and two ends of the connecting rod 73 are respectively hinged with the movable tracks 3 and the sliding blocks 71. In a similar manner, the movable rail 3 can be driven to change track by driving the sliding block 71 to linearly move along the guide rod.
The rail traction and orbital change can be realized through the haulage rope by adopting the two modes, and the specific mode is to set up a change rail traction system, the change rail traction system comprises a winch 81, an end reverse wheel 82 and a change rail haulage rope 83, the change rail haulage rope 83 is wound on the winch 81 and the end reverse wheel 82, the change rail haulage rope 83 is divided into a first traction section and a second traction section by taking the winch 81 and the end reverse wheel 82 as boundaries, and sliding blocks 71 corresponding to the movable rails 3 on two sides are respectively connected with the first traction section and the second traction section. When the winch 81 is rotated, the movement directions of the first traction section and the second traction section are opposite, the two sliding blocks 71 are respectively fixed on the first traction section and the second traction section, and then the opposite movement or the opposite movement of the two sliding blocks 71 can be realized through rotating the winch 81, so that the inward orbital transfer butt joint or the outward orbital transfer separation of the movable tracks 3 on the two sides can be realized.
The test piece loading mechanism is also usually driven by equipment, so that the test piece loading mechanism is connected with the driving mechanism, and if the whole design is adopted, the test piece loading mechanism is inconvenient for a working platform to hold up the test piece loading mechanism so as to mount or receive the test piece; thus, in the embodiment shown in fig. 2, the specimen loading mechanism includes a traction trolley 61, a pallet 62, and a driving mechanism, wherein the traction trolley 61 and the pallet 62 are both lapped on the conveying track, the pallet 62 is located at one end of the traction trolley 61 near the movable track 3, the traction trolley 61 and the pallet 62 are detachably connected, and the driving mechanism is connected to the traction trolley 61.
