Background
The large concrete prefabricated part is large in size and heavy in weight, and a security and protection moving device is needed to move the large concrete prefabricated part horizontally between the large concrete prefabricated part and the ground after the large concrete prefabricated part is prefabricated. The bottom die structure in the process of prefabricating the large concrete member meets the requirement of prefabricating the member, and meanwhile, the moving and the transportation of the prefabricated member are fully considered. The large concrete prefabricated part is generally transported by adopting a security protection air bag or a trolley in a reserved groove at the bottom of the part, and the jacking part is removed and supported. The traveling system of the segment assembled bottom die trolley mainly comprises two forms of a hydraulic oil cylinder and a hydraulic motor at present. Because the oil cylinder has stable speed and low manufacturing cost, most of the prior hydraulic oil cylinders are adopted for walking. However, the conventional hydraulic oil cylinder needs to be provided with a hole on the rail during walking, so that the clamping tongue on the clamping seat can fall into the hole in the rail during walking each time. The spacing of the holes on the track is about 500m, the size of each hole is 100 × 50 rectangular holes, and the track plate is large in deformation after blanking and needs to be straightened. The clamping tongue on the clamping seat and the hole on the track have strict matching requirements, and the processing difficulty is increased.
A hole needs to be formed in the rail when the hydraulic oil cylinder which is commonly used at present walks, and the clamping tongue on the clamping seat is ensured to fall into the hole in the rail when the hydraulic oil cylinder walks every time. The spacing of the holes on the track is about 500m, the size of each hole is 100 × 50 rectangular holes, and the track plate is large in deformation after blanking and needs to be straightened. The clamping tongue on the clamping seat and the hole on the track have strict matching requirements, and the processing difficulty is increased. In chinese patent publication no: CN 204097881U discloses a bottom die trolley, which includes two parallel lower rails, the highway box girder in the above technical scheme can move vertically and horizontally on the rails through 4 bottom die trolleys and steel platforms, and forms a circular movement, so as to solve the problem of low efficacy of the traditional girder on the fixed pedestal, and the bottom die trolley has the characteristics of simple structure, high construction speed, control facilitation, reusability, energy saving and environmental protection, but the traveling system of the bottom die trolley in the above technical scheme still cannot solve the problem provided by the present invention.
A hole needs to be formed in the rail when the hydraulic oil cylinder which is commonly used at present walks, and the clamping tongue on the clamping seat is ensured to fall into the hole in the rail when the hydraulic oil cylinder walks every time. The spacing of the holes on the track is about 500m, the size of each hole is 100 × 50 rectangular holes, and the track plate is large in deformation after blanking and needs to be straightened. The clamping tongue on the clamping seat and the hole on the track have strict matching requirements, and the processing difficulty is increased. In chinese patent publication no: CN 106042169 a discloses a novel box girder bottom die system, which includes a bottom die trolley installed on a preset rail, and a bottom die is connected to the bottom die trolley, the above technical scheme has the advantages of simple structure, convenient processing and use, and capability of adjusting the position and the inclination angle of the bottom die more effectively according to the requirements of different sections of an ultrahigh twisted bridge in a large-span small-radius bridge, but the present common hydraulic cylinder needs to open a hole on the rail for walking, so as to ensure that the latch tongue on the clamp seat falls into the hole in the rail for every walking. The spacing of the holes on the track is about 500m, the size of each hole is 100 × 50 rectangular holes, and the track plate is large in deformation after blanking and needs to be straightened. The clamping tongue on the clamping seat and the hole on the track have strict matching requirements, and the problem of increasing the processing difficulty still cannot be solved.

In chinese patent publication no: CN 109386509B discloses hydraulic traction system that platform truck marchd, solves the hydraulic traction system that the platform truck marchd and can not pinpoint, the problem that factor of safety is low. However, the track of the technical scheme still adopts the track with the holes, and the technical scheme still adopts the mode that the clamping tongues are matched with the holes in the track, so that holes are required to be formed in the track for the current common hydraulic oil cylinder provided by the invention to walk, and the clamping tongues on the clamping seats are ensured to fall into the holes in the track during each walking. The spacing of the holes on the track is about 500m, the size of each hole is 100 × 50 rectangular holes, and the track plate is large in deformation after blanking and needs to be straightened. The clamping tongue on the clamping seat and the hole on the track have strict matching requirements, and the problem of increasing the processing difficulty still cannot be solved.
Therefore, the invention urgently needs a device which can ensure that the clamping seat can be clamped normally, finish the walking action and reduce the relevance between the clamping seat and the track.
