Abstract
The utility model discloses a ceiling turning structure for a high-altitude manned operating platform of tunnel equipment. The ceiling turning structure comprises an operating platform, a ceiling, a connecting rod, a rocker arm and an oil cylinder, wherein the ceiling is rotatably connected with the operating platform; one end of the connecting rod is rotatably connected with the ceiling; the other end of the connecting rod is rotatably connected with the rocker arm; the other end of the rocker arm is rotatably connected with the operating platform; one end of the oil cylinder is hinged with the operating platform; and the other end of the oil cylinder is connected with a connected end of the connecting rod and the rocker arm. The ceiling turning structure provided by the utility model has the advantages of simple structure, low cost, simple and direct control and positioning, low demand on manufacturing precision and convenience in mounting.
Description
Technical field
The utility model belongs to the constructing tunnel equipment technical field, particularly a kind of ceiling overturn structure that is used for the manned working platform in tunnel device high-altitude.
Background technology
In the constructing tunnel; Usually need the constructor to remove to check section to tunnel cross-section; To the rig location rendrock is installed perhaps; And the manned working platform in high-altitude just can let the constructor conveniently on whole tunnel cross-section, work back and forth, at some multi-arm jumbo, on the perhaps special-purpose explosive loading truck the manned working platform in high-altitude can be installed all.In tunnel environment, the manned working platform in these high-altitudes generally all has ceiling, not only can prevent the harm of falling rocks to personnel and equipment, and the personnel that can prevent run into the top, hole.But this ceiling can influence operating personnel's sight line; The withdrawal so in needs, just will overturn; The general at present modes such as hydraulic pressure tilt cylinder or hydraulic motor acceleration and deceleration machine that adopt drive the ceiling upset; But these hydraulic part costs are all than higher, and the utility model provides a kind of overturn structure of ceiling cheaply.Use comparatively cheap small oil tank to drive, adopt the rocker-arm link structure to increase flip angle, reach instructions for use.
The utility model content
The purpose of the utility model is exactly to above-mentioned prior art problems, and a kind of ceiling overturn structure that is used for the manned working platform in tunnel device high-altitude is provided.
The purpose of the utility model realizes through following technical proposals:
A kind of ceiling overturn structure that is used for the manned working platform in tunnel device high-altitude; Comprise working platform, ceiling, connecting rod, rocking arm and oil cylinder, said ceiling is rotatably connected on the working platform, and connecting rod one end and ceiling are rotationally connected; The other end and rocking arm are rotationally connected; the other end of rocking arm is rotatably connected on the working platform, and oil cylinder one end and working platform are hinged, and the other end is connected the link of connecting rod and rocking arm.
As preferably, said working platform be one can be manned the framework of band guardrail.
As preferably, said oil cylinder carries hydraulic lock, can make ceiling stable be parked in the optional position in the flip angle.
As preferably, said oil cylinder is small-sized oil cylinder.The utility model adopts cheap small-sized oil cylinder, can effectively reduce manufacturing cost.
The beneficial effect of the utility model is: simple in structure, with low cost, the control location is directly simple, and the accuracy of manufacture requires low, easy for installation.
Description of drawings
Fig. 1 is the perspective view of the utility model;
Fig. 2 is the utility model ceiling deployed condition sketch map;
Fig. 3 is the utility model ceiling rollover states sketch map.
The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing the utility model is further described.
Like Fig. 1, Fig. 2, shown in Figure 3, a kind of ceiling overturn structure that is used for the manned working platform in tunnel device high-altitude comprises working platform 1, ceiling 2, connecting rod 3, Rocker arm 4 and oil cylinder 5.Working platform 1 be one can be manned the framework of band guardrail.Ceiling 2 is rotatably connected on the working platform 1 through bearing pin; Connecting rod 3 one ends are rotationally connected through bearing pin and ceiling 2; The other end and Rocker arm 4 are rotationally connected; the other end of Rocker arm 4 is rotatably connected on the working platform 1 through bearing pin, and oil cylinder 5 one ends are hinged on the working platform 1, and the other end is connected on the common connecting axle of connecting rod 3 and Rocker arm 4.
The utility model adopts cheap small-sized oil cylinder, can effectively reduce manufacturing cost.
Said oil cylinder 5 carries hydraulic lock, can make ceiling stable be parked in the optional position in the flip angle.
The action principle of the utility model is following:
As shown in Figure 3, oil cylinder 5 withdrawals rotate counterclockwise Rocker arm 4, and drivening rod 3 moves downward simultaneously, and connecting rod 3 pulling ceilings 2 overturn around the bearing pin that is connected on the working platform 1 counterclockwise, and this moment, ceiling 2 was in rollover states.As shown in Figure 2, on the contrary oil cylinder 5 stretches out Rocker arm 4 is clockwise rotated, and overturns clockwise around the bearing pin that is connected on the working platform 1 thereby pull bar 3 drives ceiling 2, and this moment, ceiling 2 was in deployed condition.The stroke of oil cylinder 5 has determined the angle of ceiling 2 upsets.And carry the oil cylinder 5 of hydraulic lock, can make ceiling 2 stable be parked in the optional position in the flip angle.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
