Background

In the tunnel construction process, the arch frame trolley is important supporting equipment in the initial construction period. In order to ensure the running stability of the arch frame trolley, the weight of the whole machine needs to be uniformly distributed, so that the arm frame base is often arranged at one end of the whole trolley, the range which can be reached by the arm frame during construction is very limited, and therefore, a sliding trolley needs to be used for moving the arm frame, on one hand, the construction range of equipment can be expanded, and the longitudinal working range of the equipment is expanded under the condition that the equipment does not need to be moved by the whole machine; on the other hand, the position of the arm support can be moved through the sliding trolley, the mass center of the whole trolley is changed, and the balance and the stability of the whole trolley are guaranteed.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the utility model and are not to be construed as limiting the utility model.

The hydraulic motor 3 can drive the main shaft 2 to rotate through the speed reducing mechanism 4, so that the box body 1 and the sliding trolley move together under the driving of the driving mechanism 5 on the main shaft 2, and the driving of the sliding trolley is realized. In addition, the speed reducing mechanism 4 can play a role in reducing the rotating speed and increasing the torque, and the requirement that the heavy sliding trolley needs to move slowly is met.

Specifically, the speed reduction mechanism 4 includes a first gear 41 mounted on the main shaft 2 and a second gear 42 mounted on the output end of the hydraulic motor 3, the first gear 41 meshes with the second gear 42, and the number of teeth of the first gear 41 is greater than that of the second gear 42. When the hydraulic motor 3 drives the second gear 42 to rotate, the second gear 42 drives the first gear 41 to rotate, and the main shaft 2 correspondingly rotates, so that power input is realized. Since the number of teeth of the first gear 41 is greater than that of the second gear 42, the rotation speed of the main shaft 2 is less than that of the second gear 42, so that the torque of the main shaft 2 can be increased.

Specifically, the driving mechanism 5 includes a driving sprocket 51, the driving sprocket 51 is mounted on the main shaft 2, a driven sprocket 52 is further connected to the inside of the box 1 through a bearing, a chain 53 is connected between the driving sprocket 51 and the driven sprocket 52 in a transmission manner, and both ends of the chain 53 are fixed to a fixed object. When the main shaft 2 rotates the driving sprocket 51, the chain 53 moves between the driving sprocket 51 and the driven sprocket 52. Because both ends of the chain 53 are fixed with the fixed object, the box body 1 and the sliding trolley move relative to the chain 53, and the sliding trolley is reliably driven.

The number of the driven sprockets 52 is two, the two driven sprockets 52 are respectively arranged on both sides of the driving sprocket 51, and the chain 53 is arranged on the opposite side of the driving sprocket 51 and the driven sprockets 52. The driving chain wheel 51 and the driven chain wheel 52 can be reliably meshed with the chain 53, and accurate transmission is guaranteed. The two driven sprockets 52 can tension the chain 53, ensuring reliable meshing between the chain 53 and the driving sprocket 51.

Furthermore, a speed reducer 6 is connected to an output shaft of the hydraulic motor 3, and a speed reduction mechanism 4 is connected between an output end of the speed reducer 6 and the main shaft 2.
