Abstract
The utility model discloses a screw rod a tunnel trolley, mainly relating to a hydraulic screw for a tunnel trolley and solving the disadvantages of the existing hydraulic screw of a tunnel trolley. A connecting plate1 is connected on the trolley, when the trolley arrives at a new working face, a hydraulic cylinder needs to send a template to a definite working site, a sliding sleeve on the screw slides on a guide post and works orderly along with the hydraulic cylinder. When the template reaches the desirable place, a locknut6 is rotated forward to lock the sliding sleeve, and while maintaining the relaxed state, a handle8 is rotated to enable the screw to work to finely adjust the position of the template. After concrete is poured, the template needs to be dismantled; the locknut is unscrewed through a spanner; the sliding sleeve slides on the guide post; and the template can extend and retract along with the work of the hydraulic cylinder. The operation is simple and can be done by only one operator, the work efficiency is high, and the operating process is safe and reliable.
Description
Technical field
The utility model tunnel chassis leading screw relates generally to a kind of tunnel chassis hydraulic pressure leading screw.
Background technology
At present, tunnel chassis hydraulic pressure leading screw must be taken apart when hydraulic cylinder works, treats leading screw to be installed after hydraulic cylinder is delivered to concrete operating position with template again, treat that concreting is finished after, to remove leading screw earlier, hydraulic cylinder just can work on.A chassis generally need be installed 100 multi-filament thick sticks, and a rhizoid thick stick probably has more than 30 jin of weight, and installation and removal are trouble very, workload is very big, and the template intermediate space is limited in the tunnel, and it is more that potential safety hazard is unloaded in the process in the case installation and dismantling, and programming is slow.
Summary of the invention
The utility model tunnel chassis hydraulic pressure leading screw has solved the drawback of existing chassis hydraulic pressure leading screw, leading screw and junction plate are fixed, adjusting nut and leading screw welding, tube connector is welded in adjusting nut and slip cap, slip cap is in the periphery of guide pillar, handle is cemented on the tube connector, and locking nut is at the front end of slip cap.When hydraulic cylinder works, do not need to remove leading screw, only need unclamp locking nut and returns or tighten, simple to operate, high efficiency, people just can complete operation, and leading screw, nut all keep and being connected of chassis, and operation process is safe and reliable.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
In the diagram: 1 junction plate, 2 leading screws, 3 adjusting nuts, 4 tube connectors, 5 slip caps, 6 locking nuts, 7 guide pillars, 8 handles.
The specific embodiment
In conjunction with the accompanying drawings the utility model is described further;
The utility model tunnel chassis hydraulic pressure leading screw, by: junction plate 1, leading screw 2, adjusting nut 3, tube connector 4, slip cap 5, locking nut 6, guide pillar 7, handle 8 are formed.Leading screw 2 is fixed with junction plate, adjusting nut 3 and leading screw 2 welding, and tube connector 4 is welded in adjusting nut 3 and slip cap 5, and slip cap 5 is in the periphery of guide pillar 7, and handle 8 is cemented on the tube connector 4, and locking nut 6 is at the front end of slip cap 5.
In concrete enforcement, junction plate 1 is connected in chassis, and when chassis arrived new work plane, hydraulic cylinder needed template is delivered to concrete operating position, and simultaneously, slip cap slides on guide pillar on the leading screw, along with the orderly work of hydraulic cylinder; After template arrived desired location, rotational lock nut 6 locking slip caps kept the relaxation state forward, and turning handle 8 makes leading screw work carry out the fine setting of template position.The concrete pouring template that finishes needs to remove, and unclamps locking nut with spanner, and slip cap slides on guide pillar, along with the flexible of template finished in the work of hydraulic cylinder.
Claims (1)
1, tunnel chassis hydraulic pressure leading screw, form by junction plate (1), leading screw (2), adjusting nut (3), tube connector (4), slip cap (5), locking nut (6), guide pillar (7), handle (8), it is characterized in that: leading screw (2) is fixed with junction plate, adjusting nut (3) and leading screw (2) welding, tube connector (4) is welded in adjusting nut (3) and slip cap (5), slip cap (5) is in the periphery of guide pillar (7), handle (8) is cemented on the tube connector (4), and locking nut (6) is at the front end of slip cap (5).
