Description
Technical field
The present invention relates to the top board chain trench covering mechanism of a kind of mechanical engineering field, particularly relate to a kind of top board automatic covering mechanism of chain trench.
Background technology
That runs on ground guide at present automatically moves workbench, generally requires the cable using drag chain to carry and flexible pipe provides power supply and source of the gas for it.For making in mobile working platform running, drag chain is unlikely to exposed and generally drag chain can be arranged in trench, and renovate on plate lid with gemel on the ground, and renovating plate can along with the operation of mobile working platform covers automatically or opens.
But renovate plate thickness of slab and be generally 20mm, structure bulky, and running can be subject to laterally dig power, this easily makes two adjacent plates of renovating occur occlusion not cover smoothly, causes being broken by mobile working platform.
Summary of the invention
It is an object of the invention to provide a kind of automatic covering and light can the top board automatic covering mechanism of chain trench of even running.
For achieving the above object, the technical solution used in the present invention is:
A kind of top board automatic covering mechanism of chain trench, including upper bracket, lower carriage and top board chain, it is characterized in that: lower carriage is arranged on mobile working platform by fixing bolt and spring, upper bracket is arranged on above lower carriage by adjusting bolt, upper bracket and lower carriage are respectively a pair that position relationship is symmetrical, being connected by bar between two upper brackets and between two lower carriages, grooved roller is arranged between two upper brackets by axle, and two flat rollers are separately mounted to the two ends of two lower carriages by axle；Top board chain covers on trench, two ends are fixed, top board chain forms arch through flat roller and grooved roller, the lower surface of top board chain is pressed in above grooved roller, the upper surface of top board chain is pressed in below two flat rollers, and in trench, the cable in drag chain and flexible pipe are by entering mobile working platform below the arch of top board chain formation.
According to the described top board automatic covering mechanism of chain trench, it is characterised in that: described grooved roller can be multiple, and middle grooved roller position is higher than both sides.
According to the described top board automatic covering mechanism of chain trench, it is characterised in that: described flat roller is provided with two wheels.
According to the described top board automatic covering mechanism of chain trench, it is characterised in that: the distance between said two upper bracket is adjusted by adjusting bolt.
Advantages of the present invention effect is in that: can automatically cover, portable construction, operates steadily reliable, solves the heavy problem of prior art, solve in prior art two adjacent plates of renovating and occlusion occurs and the problem that can not cover smoothly, there is good commercial value.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
The present invention is as Figure 1-3, a kind of top board automatic covering mechanism of chain trench, including upper bracket 1, lower carriage 3 and top board chain 8, it is characterized in that: lower carriage 3 is arranged on mobile working platform by fixing bolt 7 and spring 6, upper bracket 1 is arranged on above lower carriage 3 by adjusting bolt 5, upper bracket 1 and lower carriage 3 are respectively a pair that position relationship is symmetrical, connected by bar between two upper brackets 1 and between two lower carriages 3, grooved roller 2 is arranged between two upper brackets 1 by axle, and two flat rollers 4 are separately mounted to the two ends of two lower carriages 3 by axle；Top board chain 8 covers on trench, two ends are fixed, top board chain 8 forms arch through flat roller 4 and grooved roller 2, the lower surface of top board chain 8 is pressed in above grooved roller 2, the upper surface of top board chain 8 is pressed in below two flat rollers 4, and in trench, the cable in drag chain and flexible pipe are by entering mobile working platform below the arch of top board chain 8 formation.According to the described top board automatic covering mechanism of chain trench, it is characterised in that: described grooved roller 2 can be multiple, and middle grooved roller 2 position is higher than both sides.According to the described top board automatic covering mechanism of chain trench, it is characterised in that: described flat roller 4 is provided with two wheels.According to the described top board automatic covering mechanism of chain trench, it is characterised in that: the distance between said two upper bracket 1 is adjusted by adjusting bolt 5.
As Figure 1-3, the automatic covering mechanism of top board chain trench, including top board chain 8, upper bracket 1, lower carriage 3, grooved roller 2, flat roller 4, fixing bolt 7, spring 6, adjusting bolt 5 for the operation principle of the present invention.Flat roller 4 is arranged on lower carriage 3, flat roller 4 can flexible rotating, lower carriage 3 is fixed on mobile working platform by fixing bolt 7 and spring 6, grooved roller 2 is arranged on upper bracket 1, grooved roller 2 can flexible rotating, upper bracket 1 and lower carriage 3 are connected by adjusting bolt 5, the relative distance of upper bracket 1 and lower carriage 3 can be passed through adjusting bolt 5 and regulate, top board chain 8 covers on trench, and two ends are fixed, and forms arch through flat roller 4 and grooved roller 2.Allow the cable in the drag chain being arranged in trench and flexible pipe be overarched by top board chain and enter mobile working platform below, such that it is able to give mobile working platform offer power supply and source of the gas.When mobile working platform runs, the arch that top board chain is formed can be walked along with mobile working platform, and the top board chain of the part beyond mobile working platform can cover on trench naturally because of gravity, thus protecting drag chain, cable and flexible pipe.Top board chain only has 3mm thick, and running is the same with chain drive process steadily reliable, and the general chain drive of load ratio is gently a lot.In sum, compared with prior art, its structure is lighter and operates steadily reliable for the automatic covering mechanism of top board chain trench.Can automatically cover, portable construction, operate steadily reliable, solve the heavy problem of prior art, solve in prior art two adjacent plates of renovating and occlusion occurs and the problem that can not cover smoothly, there is good commercial value.
Embodiment described above is only that the preferred embodiment of the present invention is described; not design and the protection domain of the present invention is defined; under the premise without departing from design concept of the present invention; various modification that in this area, technical scheme is made by ordinary skill technical staff and improvement, all should fall into protection scope of the present invention.
