Description

Technical Field

[0001] The utility model relates to the technical field of trolley translation, and particularly relates to a translation structure for the outer formwork of a lining trolley. Background Art

[0002] Lining trolleys are usually used for lining construction of open tunnels. During the construction process, it is necessary to adjust the position of the formwork on the lining trolley to ensure the accurate position of the open tunnel during pouring. The existing lining trolleys usually adopt the method of lower part translation to adjust the position of the lining trolley formwork. Since the formwork is an arc structure, translating the lower part easily causes the formwork to deform, resulting in unqualified pouring of the open tunnel. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a translation structure for the outer formwork of a lining trolley, which can effectively ensure that the formwork does not deform during translation.

[0006] Further, the hydraulic cylinder is arranged parallel to the transverse connecting beam in the same direction. Its tail is detachably connected to the transverse connecting beam through a first hinge ear, and the telescopic end is detachably connected to the longitudinal beam through a second hinge ear.

[0007] Further, a sliding seat is fixedly connected to the lower end of the longitudinal beam; a through groove is formed in the sliding seat; the upper end of the translation seat is in rolling connection with the through groove.

[0008] Further, the translation seat includes a vertical support, an upper support, a fixed shaft, and a first bearing; the upper end of the vertical support is fixedly connected to the lower end of the upper support; the fixed shaft penetrates through the upper part of the upper support and is fixedly connected to the upper support; two first bearings are coaxially fixedly connected to both ends of the fixed shaft; the first bearing can roll relative to the through groove.

[0009] Further, the lower end of the vertical support is fixedly connected to a first connecting plate.

[0010] Further, a diagonal brace is fixedly connected to the upper part of the vertical support.

[0011] Further, the lower end of the diagonal brace is fixedly connected to a second connecting plate.

[0012] Advantages of the present utility model:

[0013] Through the telescopic movement of the hydraulic cylinder, the transverse connecting beam and the translation seat move relatively; since there are a translation seat and a sliding seat between the longitudinal beam and the translation seat and the first bearing is used to roll in the through groove, the friction of the movement is effectively reduced, ensuring the smooth progress of the translation; by connecting the translation seat with the upper part of the trolley formwork, this method is a hanging structure, which is conducive to leaving space inside the trolley for other processes and improving the efficiency. The trolley formwork is not easily deformed, which is conducive to reducing the economic cost. Description of the drawings

[0023] The following further describes the specific embodiments of the present utility model with reference to the drawings. It should be noted here that the description of these embodiments is for helping to understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] Refer to Figures 1-6As shown in the figure, a translation structure for the outer formwork of a lining trolley includes longitudinal beams 1, hydraulic cylinders 2, transverse connecting beams 3, and translation seats 4. There are two longitudinal beams 1 symmetrically arranged. At the lower parts of both ends of each longitudinal beam 1, there are translation seats 4. The translation seats 4 can move in the vertical direction perpendicular to the radial direction of the longitudinal beam 1. A transverse connecting beam 3 is detachably connected between the translation seats 4 arranged oppositely on the two longitudinal beams 1. A hydraulic cylinder 2 is detachably connected between the transverse connecting beam 3 and the longitudinal beam 1.

[0025] It should be noted that the longitudinal beams 1 are provided to facilitate the connection between the translation structure of the outer formwork of the lining trolley and the movement of the lining trolley and support the position movement of the trolley formwork. The hydraulic cylinders 2 can facilitate the upper parallel movement of the lining trolley formwork from above to ensure the accuracy of the formwork position. The transverse connecting beam 3 effectively ensures the stability of the longitudinal beam 1 and can facilitate the fixing of the hydraulic cylinder 2 for convenient translation. When the translation structure of the outer formwork of the lining trolley is provided with 4 hydraulic cylinders 2 during the movement, when the hydraulic cylinder 2 on one side of a longitudinal beam 1 stretches, the hydraulic cylinder 2 on the other side of the longitudinal beam 1 contracts, thereby ensuring the synchronous movement of the transverse connecting beam 3 and the translation seat 4 in the same direction.

[0026] Specifically, the hydraulic cylinder 2 is arranged parallel to the transverse connecting beam 3 in the same direction. Its tail is detachably connected to the transverse connecting beam 3 through a first hinge ear 5, and the telescopic end is detachably connected to the longitudinal beam 1 through a second hinge ear 6. The translation seat 4 can be connected to the trolley formwork to ensure the smooth progress of the movement.

[0027] Specifically, a sliding seat 7 is fixedly connected to the lower end of the longitudinal beam 1. A through groove 71 is provided on the sliding seat 7. The through groove 71 is in rolling connection with the upper end of the translation seat 4. The through groove 71 can facilitate the movement of the translation seat 4 in the sliding seat 7.

[0028] Specifically, the translation seat 4 includes a vertical support 41, an upper support 42, a fixed shaft 43, and a first bearing 44. The upper end of the vertical support 41 is fixedly connected to the lower end of the upper support 42. The fixed shaft 43 penetrates through the upper part of the upper support 42 and is fixedly connected to the upper support 42. Two first bearings 44 are coaxially fixedly connected to both ends of the fixed shaft 43. The first bearing 44 can roll relative to the through groove 71. The vertical support 41 is the main part connected to the trolley formwork. The upper support 42 can limit the fixed shaft 43. The cooperation of the fixed shaft 43 and the first bearing 44 can drive the translation seat 4 to move smoothly inside the sliding seat 7.

[0029] Specifically, to facilitate the connection between the vertical support 41 and the trolley formwork, the lower end of the vertical support 41 is fixedly connected to a first connecting plate 46.

[0030] Specifically, to increase the connection strength, a diagonal brace 45 is fixedly connected to the upper part of the vertical support 41.

[0031] Specifically, to facilitate the connection between the diagonal brace 45 and the trolley formwork, a second connecting plate 47 is fixedly connected to the lower end of the diagonal brace 45.

[0032] The working principle of the present utility model:

[0033] When the formwork of the lining trolley needs to be translated, through the telescopic movement of the hydraulic cylinder 2, relative movement occurs between the transverse connecting beam 3 and the translation seat 4; since a translation seat 4 and a sliding seat 7 are provided between the longitudinal beam 1 and the translation seat 4 and the first bearing 44 is used to roll in the through groove 71, the friction of the movement is effectively reduced, ensuring the smooth progress of the translation; the translation seat 4 is connected to the upper part of the trolley formwork, and this method is a hanging structure, which is beneficial to leaving space inside the trolley for the operation of other processes.

[0034] The above has described in detail the embodiments of the present utility model in conjunction with the accompanying drawings, but the present utility model is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present utility model, various changes, modifications, substitutions and variations of these embodiments still fall within the protection scope of the present utility model.
