Problems solved by technology

[0003] The shortcomings of the above two chutes are: 1. The size of the long chute needs to be measured accurately to meet the inverted arch concrete pouring of a certain section.
But when pouring the inverted arch concrete of other tunnel sections with different widths, the chute will be too short or too long, and the versatility of the chute cannot be realized. Time-consuming and labor-intensive, which affects construction efficiency; 3. Use the long chute on the trestle trolley for construction. The manufacturing cost of this device itself is relatively high. When it is necessary to change the position for pouring, it is necessary to start the trestle trolley, resulting in high mobile costs for the device. ; Most of the four-chute lifts use hydraulic devices, with complex structures and high costs

Embodiment Construction

[0020]The present invention will be further described in detail below in conjunction with the drawings and specific embodiments of the specification.

[0021]Figure 1 to Figure 4An embodiment of the movable chute based on the trestle bridge of the present invention is shown. The movable chute based on the trestle bridge of this embodiment includes a base 2 that can move along the length of the trestle 1, and a main hinged on the base 2 The chute 3 and the base 2 are arranged on the side of the trestle 1, the lower end of the main chute 3 is connected with at least one sliding chute 4, and the upper end of the main chute 3 is connected with a rotating chute 5.

[0022]The movable chute based on the trestle bridge has its own base 2 that can move along the length of the trestle bridge 1. The base 2 can drive the main chute 3, sliding chute 4 and rotating chute 5 to move along the side of the trestle bridge 1, which is convenient for changing the construction location without With the aid of...

Abstract

The invention discloses a movable chute based on a trestle. A base capable of moving in the length direction of the trestle and a main chute body hinged to the base are included, the base is arrangedon the side edge of the trestle, the lower end of the main chute body is in butt joint with at least one sliding chute body, and the upper end of the main chute body is in butt joint with a rotating chute body. The invention further provides a trestle comprising the movable chute. The movable chute based on the trestle and the trestle have the advantages that the structure is simple, universalityis good, and usage is flexible.

Description

Technical field[0001]The invention relates to equipment for tunnel concrete pouring, in particular to a movable chute and trestle bridge based on a trestle bridge.Background technique[0002]When concrete construction is carried out in the tunnel, it is necessary to pour the curved invert layer concrete first, and then pour the upper filling layer concrete. When the inverted arch formwork is used for pouring concrete of the curved invert layer, the concrete needs to be poured from both sides of the tunnel. Due to restrictions on construction requirements, production costs and production techniques, the chute for pouring concrete here is different. There are mainly two kinds of more common ones: 1. Only one long chute is simply made for pouring from both sides of the tunnel. When you need to change the position along the tunnel driving direction for pouring, you need to lift it up manually; 2. Use a long chute and fix the long chute to the trestle trolley. When you need to change the p...
