DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor are involved in the protection scope of the utility model.

[0027] As Figures 1-7 shown, a box girder assembly type mobile pedestal, including mobile base 1, the both ends of the mobile base 1 are insertion end 11 and connecting end 12 respectively, the insertion end 11 includes the containing groove 111 opened on the end face, the containing groove 111 is set along the mobile base 1 movement direction, its inside slidably connected with connecting rod 112, the connecting rod 112 is opened with connecting hole 113, the side wall of the containing groove 111 is opened with locking hole 114 matched with connecting hole 113;The connecting end 12 includes pressure covering 121 and supporting piece 122, the pressure covering 121 and supporting piece 122 are downwardly buckled to form connecting groove 123, the connecting groove 123 and containing groove 111 position shape are all correspondingly matched, the supporting piece 122 is fixed with mobile base 1, the pressure covering 121 is fixed with supporting piece 122 through locking mechanism.

[0028] In this embodiment, the mobile base adopts a modular assembly design, and two adjacent mobile bases can be connected to each other through the insertion end 11 and the connecting end 12. Specifically, the two mobile bases are first placed on the same running track by a hoisting mechanism and are ensured to be in the same direction, so that the connecting end 12 and the insertion end 11 of the two mobile bases 1 are oppositely arranged at the connection position of the two mobile bases. The connecting rod 112 is pulled out of the accommodating groove 111, and the pressing cover 121 is lifted to make the connecting rod 112 enter the lower part connecting groove 123 inside the supporting piece 122. After reaching the designated position, the pressing cover 121 is lowered and locked to fix the connecting rod 112. At this time, the connecting hole 113 on the connecting rod 112 is aligned with the locking hole 114 on the side wall of the accommodating groove 111, and is locked by the locking mechanism to ensure the stable connection of the two mobile bases 1 through the connecting rod 112.

[0029] Through the insertion end 11 and the connecting end 12, two mobile bases can be quickly spliced or disassembled, and the load-bearing strength of the mobile base is ensured, so that the production requirements of precast beams of different lengths can be met, the construction efficiency and flexibility are significantly improved, the construction cost is reduced, and the adaptability is enhanced. At the same time, the mobile base can more accurately match the length of the beam, and the construction quality and safety can be improved.

[0030] As shown in Figure 3 The two sides of the connecting rod 112 are fixed with a push-pull rod 115, the side wall of the accommodating groove 111 is provided with a push-pull rail 1111 inward from the end face along the movement direction of the mobile base 1, each push-pull rod 115 is inserted into the push-pull rail 1111 on the side where it is located, and the pressing cover 121 and the supporting piece 122 are buckled to form a limiting hole 124 for accommodating the push-pull rod 115. And the push-pull rod 115 is fixed with an external thread. The main function of the push-pull rod 115 is to facilitate the pushing of the connecting rod 112 as a force point, and to improve the efficiency of the entire assembly connection process. At the same time, the external thread can match the nut and be locked by the push-pull rail 1111 to facilitate locking at a certain node of the connecting rod 112 to prevent it from sliding. And the limiting hole 124 can well limit and fix the push-pull rod 115, which further increases the connection strength of the accommodating groove 111 to the connecting rod 112 in addition to the pressure of the pressing cover 121 and the supporting piece 122 to the connecting rod 112.

[0031] Meanwhile, in order to prevent the connecting rod 112 from being pulled out when it is not working, the anti-pulling plate 116 is arranged on the end face of the insertion end 11 and can slide on the end face to open or close the port of the accommodating groove 111. The anti-pulling plate 116 is provided with a fixing hole 1161, and the end face of the insertion end 11 is provided with two fixing grooves 117 matched with the fixing hole 1161. When the anti-pulling plate 116 opens or closes the accommodating groove 111, the fixing hole 1161 is matched with one fixing groove 117 respectively and is locked by a locking mechanism. The anti-pulling plate 116 is fixed with a push-pull handle 1162 which is a downwardly recessed circular arc structure, facilitating manual movement of the anti-pulling plate 116.

[0032] In addition, the connecting hole 113 of the connecting rod 112 has a plurality of connecting holes 113, which can adapt to the extension length of the connecting rod 112, so as to adjust the overall length of the mobile base after assembly, and further adapt to different beam lengths.

[0033] As shown in Figures 4-5 The side of the pressing cover 121 in contact with the mobile base 1 is fixed with a guide sliding block 1211, and the mobile base 1 is provided with a guide sliding track 13 matched with the guide sliding block, so as to facilitate lifting of the pressing cover 121. In actual operation, only a certain height needs to be lifted, and the connecting rod 112 can be inserted conveniently.

[0034] As shown in Figure 1 The mobile base further comprises a support platform 2 and a support beam 3. The top of the support beam 3 is fixed with the support platform 2, and the bottom is slidably connected with the mobile base 1 through a guide sliding block 31. The mobile base 1 is provided with a guide sliding track 14 matched with the guide sliding block 31 along the length direction. Since the overall length of the mobile base changes after assembly, the distribution adjustment position of the support beam 3 can be adjusted through the guide sliding track 14, so as to ensure that the entire mobile base is balanced after assembly. In order to ensure the connection strength, the locking mechanism is preferably bolted.

[0035] The above is only a preferred embodiment of the present application and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
