Description

Technical Field

[0001] The utility model belongs to the technical field of subway shield tunnel construction, and particularly relates to a horizontal translation device suitable for large-weight material equipment. Background Technique

[0002] In recent years, shield technology has been widely applied in urban underground pipelines, tunnels and other projects. Affected by the environmental space, technologies such as horizontal and vertical translation and pushing in the air of shield machines have also become one of the common technologies in shield construction due to their advantages such as high efficiency, accuracy and safety. Vertical translation is applied more frequently, and generally uses track transportation, pushing, etc. Horizontal translation is less common. Generally, the guiding idea for the translation of the shield body and the rear supporting equipment of the shield tunneling machine is to use a hydraulic cylinder to push the bracket. The receiving bracket is installed and fixed on the steel plate. The bottom of the bracket must be leveled with a steel plate and connected into a whole. After the receiving frame on the shield machine, the hydraulic cylinder is used to push the whole bracket to translate. Butter is smeared on the steel plate to reduce the frictional resistance between the moving bracket and the steel plate. After the preparatory work is completed, the translation construction is carried out. The subsequent translation principle of the trolley is the same as that of the shield body translation. After the trolley is vertically lifted by a jack, steel plates are laid at the bottom. At the same time, the wheels at the bottom of the trolley are cut off, and the trolley is connected to the laid steel plates into a whole, and then the trolley is horizontally translated by a jack. At the same time, a platform needs to be erected for the trolley translation. The platform is erected with I20 channel steel, and steel plates are laid on it for the trolley to fall and be placed stably. There are problems of cumbersome operation, poor safety and low efficiency. Content of the Utility Model

A vehicle-mounted fixed track perpendicular to the trolley traveling and transporting tracks is laid on the cross beams. When the first flat car travels to the tunnel, the vehicle-mounted fixed track can be docked with the connecting track at the entrance of the tunnel. Both the vehicle-mounted fixed track and the connecting track at the entrance of the tunnel include two flat car running tracks arranged in the center and two trolley running tracks arranged outside the flat car running tracks. A second flat car is arranged on the flat car running tracks. The second flat car is an electric vehicle, which can drive the equipment to move or carry materials alone.

[0005] Furthermore, both the first flatbed truck and the second flatbed truck include a vehicle body.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] In order to better understand the purpose, structure and function of the present utility model, the following further describes in detail a horizontal translation device for large-weight material equipment of the present utility model with reference to the accompanying drawings.

[0019] As Figures 1 to 3 shown, a horizontal translation device for large-weight material equipment includes two sets of trolley traveling and transporting tracks 1 arranged in parallel at a certain distance. A first flatbed trolley 2 is arranged on the trolley traveling and transporting track 1. The first flatbed trolley 2 includes a vehicle body 21. The front and rear ends of the vehicle body 21 are horizontal sections at the same height, and the middle part is a concave section lower than the horizontal section. Two pairs of track wheels 22 are respectively arranged below the front and rear horizontal sections.

[0020] A steel reinforcement connecting piece 3 is arranged on the first flatbed trolley 2. The steel reinforcement connecting piece 3 includes a longitudinal beam 31 and a cross beam 32. The longitudinal beam 31 is composed of two parallel I-beams, and the cross beam 32 is a single I-beam. The longitudinal beam 31 is respectively placed parallel to the horizontal sections on both sides of the two first flatbed trolleys 2. The cross beam 32 is perpendicular to the longitudinal beam 31 and is fixedly arranged at intervals above the longitudinal beam 31. A vehicle-mounted fixed track 4 perpendicular to the trolley traveling and transporting track 1 is laid on the cross beam 32. When the first flatbed trolley 2 travels to the tunnel 10, the vehicle-mounted fixed track 4 can be butted with the connection track 11 at the entrance in the tunnel 10. Both the vehicle-mounted fixed track 4 and the entrance connection track 11 include two flatbed trolley walking tracks arranged in the center and two trolley walking tracks arranged outside the flatbed trolley walking tracks. A second flatbed trolley 12 is arranged on the flatbed trolley walking tracks. The second flatbed trolley 12 is an electric vehicle and can drive the equipment to move or transport materials alone.

[0021] In this embodiment, the structure of the second flatbed trolley 12 is the same as that of the first flatbed trolley 2. The concave section in the middle is convenient for limiting when transporting materials or when fixing with the equipment. First fixed limit blocks 6 and second fixed limit blocks 7 are respectively arranged on the tracks at both ends of the trolley traveling and transporting track 1. A third fixed limit block 8 is arranged on the track of the vehicle-mounted fixed track 4 far from the tunnel 10. Movable limit blocks 9 are respectively arranged on the adjacent tracks of the vehicle-mounted fixed track 4 and the entrance connection track 11.

[0022] As Figure 1 and Figure 4As shown in the figure, the entrance of the tunnel 10 is enclosed, and the hoisting opening is set on the right side. Materials or equipment inside the tunnel 10 are transported along the connecting track 11 at the entrance to the upper part of this device.
