Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy construction processing equipment, and particularly relates to a processing and transportation device for spraying and protecting a steel bar mesh. Background Art

[0002] During the construction of a tunnel, in order to ensure safety during construction and operation, the conventional safety technical measure is to hang a steel bar mesh and spray concrete in the tunnel. The efficiency of hanging the steel bar mesh directly affects the support speed during the process of hanging the steel bar mesh and spraying in the tunnel. The traditional method is to straighten and cut the steel bars into 4 - 7m lengths outside the tunnel. Workers stand on the support trolley and fix the steel bar mesh on the rock wall one by one according to the row and column spacing of the design drawings, and tie the vertical and horizontal steel bar nodes to complete the construction of hanging the steel bar mesh. Using the traditional method to install the steel bar mesh on site in the tunnel has great construction difficulty, it is difficult to ensure the steel bar spacing, and the speed is slow.

[0003] The Chinese patent "Device for Processing and Manufacturing a Spraying and Protecting Steel Bar Mesh Sheet", application number 201821416975.2, discloses a device for processing and manufacturing a steel bar mesh sheet. Although it solves the technical problem that it is difficult to ensure the steel bar spacing, when constructing the hanging of the steel bar mesh in the tunnel, due to the limited space in the tunnel, it is necessary to manufacture the steel bar mesh outside the tunnel and transport it into the tunnel. However, due to the too large area of the steel bar mesh (a rectangular mesh with side lengths of 4 - 7m), it is not convenient to remove it from the processing and manufacturing device and transport it into the tunnel, and special lifting equipment and transportation tools are required to cooperate, which increases the construction difficulty and safety risks. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art and provide a processing and transportation device for spraying and protecting a steel bar mesh with high construction efficiency, simple operation and convenient transportation.

[0005] The technical solution adopted to solve the above technical problem is: a processing and transportation device for spraying and protecting a steel bar mesh, a left guide rail slider structure and a right guide rail slider structure are respectively arranged on the left and right sides of the base. A spraying and protecting net processing frame is arranged on the sliders of the left guide rail slider structure and the right guide rail slider structure. A left electric push rod and a right electric push rod are arranged on the base behind the spraying and protecting net processing frame. The power ends of the left electric push rod and the right electric push rod are respectively arranged at the left and right ends of the spraying and protecting net processing frame. Four pulleys distributed in a rectangle are arranged at the bottom of the base, and the pulleys are located on the slide rails on the ground, and the sliding direction of the pulleys is perpendicular to the movement direction of the sliders in the left guide rail slider structure and the right guide rail slider structure.

[0006] As a preferred technical solution, the base is of a rectangular structure, and anchor bolts are arranged at the four corners of the base.

[0007] As a preferred technical solution, positioning rods are evenly distributed on the front cross bar and longitudinal bars of the rectangular main frame body of the spraying protection net processing frame, and the positioning rods on the two longitudinal bars are symmetrically distributed, and the positioning rods on the two cross bars are symmetrically distributed.

[0008] As a preferred technical solution, the cross section of the pulley is a concave arc surface, and the track is a circular tube matching the pulley.

[0009] The beneficial effects of the present utility model are as follows:

[0010] The present utility model realizes net removal by controlling the movement of the spraying protection net processing frame through an electric push rod, reduces the labor intensity of manually handling the steel bar net, speeds up the processing speed of the steel bar net, and improves the construction efficiency.

[0011] The structure of the present utility model is simple and ingeniously designed, reducing the operation difficulty. The operator only needs to complete the processing, transportation, and net removal of the steel bar net through simple operations, enabling non-professionals to quickly get started. At the same time, it reduces additional handling and transportation links, reduces transportation costs and construction difficulty.

[0012] The base of the present utility model is provided with anchor bolts to fix the base during the processing or hoisting of the steel bar net, prevent the device from moving, and increase the safety during the construction process. Description of the Drawings

Detailed Description of the Embodiment

[0017] The present utility model will be further described in detail below in conjunction with the drawings and embodiments, but the present utility model is not limited to the following embodiments.

[0018] In Figure 1 , 2, in FIGS. 2 and 3, for the shotcrete steel mesh processing and transportation device of this embodiment, a left guide rail slider structure 7 and a right guide rail slider structure 2 are respectively and fixedly installed on the left and right sides of the base 3. A shotcrete mesh processing frame 1 is fixedly installed on the sliders of the left guide rail slider structure 7 and the right guide rail slider structure 2. On the base 3 behind the shotcrete mesh processing frame 1, a left electric push rod 9 and a right electric push rod 8 are fixedly installed. The power ends of the left electric push rod 9 and the right electric push rod 8 are respectively fixedly installed at the left and right ends of the shotcrete mesh processing frame 1. Four pulleys 5 distributed in a rectangle are fixedly installed at the bottom of the base 3. The pulleys 5 are located on the slide rails 4 on the ground. The cross-section of the pulley 5 is an inward concave arc surface, and the track is a round steel pipe matching the pulley 5. The track of this structure can use local materials and is easy to lay. The sliding direction of the pulley 5 is perpendicular to the movement direction of the sliders in the left guide rail slider structure 7 and the right guide rail slider structure 2.

[0019] The base 3 of this embodiment is a rectangular structure. Anchor bolts 6 are installed at the four corners of the base 3. When processing or hoisting the steel mesh, the base 3 is fixed to the ground through the anchor bolts 6 to prevent the base 3 from walking along the track and improve the construction efficiency.

[0020] The shotcrete mesh processing frame 1 of this embodiment is a rectangular main frame body 1-1. Positioning rods 1-2 are evenly distributed on the front sides of the upper and lower crossbars and vertical bars. The positioning rods 1-2 on the crossbars are perpendicular to the crossbars, and the positioning rods 1-2 on the vertical bars are perpendicular to the vertical bars. The positioning rods 1-2 on the two vertical bars are symmetrically distributed, and the positioning rods 1-2 on the two crossbars are symmetrically distributed. The distance between adjacent two positioning rods 1-2 is determined according to the size of the mesh holes of the required steel mesh.

[0021] The working principle of the present utility model is as follows:

[0022] First, lay the track. Select a steel pipe matching the pulley 5 locally as the guide rail, lay the track from the processing position outside the tunnel to the hanging mesh position inside the tunnel, place this processing device on the track, and fix it through the anchor bolts 6.

[0023] During processing, place a steel bar vertically on each group of symmetric positioning rods 1-2 on the upper and lower crossbars until the crossbars are vertically filled with steel bars. Then, place a steel bar horizontally on each group of symmetric positioning rods 1-2 on the left and right vertical bars until the vertical bars are horizontally filled with steel bars. Finally, spot-weld the intersections of the vertical and horizontal steel bars. When all intersections are welded, a shotcrete steel mesh is completed. Then, remove the anchor bolts 6, push the processing device to transport the shotcrete steel mesh to the hanging mesh position, hook the hook of the hoisting mechanism on the steel mesh, control the left electric push rod 9 and the right electric push rod 8 to retract, drive the shotcrete mesh processing frame 1 to move backward, disengage from the shotcrete steel mesh, and push this processing device back to the processing position to weld the next steel mesh.
