Detailed Description

Embodiments of the present utility model will be further described with reference to the accompanying drawings.

Referring to fig. 1-5, a safety protection device for a tunnel construction trestle comprises a trestle 1, wherein two channels 13 are arranged on the trestle 1, protection devices 2 are respectively arranged on two sides of the channels 13, the lower sides of the protection devices 2 are rotationally connected with the trestle 1, a driving device 3 is arranged below the protection devices 2, and the driving device 3 drives the protection devices 2 to overturn. The reversible protection devices 2 are arranged on two sides of the channel 13 of the trestle 1, so that not only can the passing safety problem of personnel be met, but also the passing safety problem of vehicles can be met, and meanwhile, the ultra-wide vehicle passing can be also met.

Referring to fig. 2, the guard device 2 includes a guard rail 21 and a rotation support shaft 22, the guard rail 21 is fixedly installed on the rotation support shaft 22, and the rotation support shaft 22 is rotatably installed on the cross beam 12 of the trestle 1 through a bearing block 23. Simple structure, easy to assemble.

Referring to fig. 2, the driving device 3 is mounted on a longitudinal beam 11 of the trestle 1, the longitudinal beam 11 is located below a cross beam 12, and the driving device 3 is a hydraulic motor or an electric reducer. In the case of the trestle itself with a hydraulic system, the hydraulic motor can be installed as the driving device 3, but when the hydraulic motor is adopted, the hydraulic pipeline is longer, and the installation is inconvenient, so that the trestle can also be driven by adopting a motor speed reducer, preferably, the motor speed reducer adopts a turbine worm speed reducer or other motor speed reducers with braking functions. In this way, the guard 2 can maintain a fixed angle after the guard 2 is turned over to the fixed angle and the driving means 3 is stopped.

Referring to fig. 2, in a preferred embodiment, the output shaft of the driving device 3 is provided with a first sprocket 31, the rotation support shaft 22 of the protection device 2 is provided with a second sprocket 33, and the chain 32 is sleeved on the first sprocket 31 and the second sprocket 33 to drive. In addition to the above-described structure, other structures such as a gear transmission may be employed, in which a gear is mounted on the rotation support shaft 22, and a gear is also mounted on the output shaft of the driving device 3, and the two gears are engaged for transmission.

Referring to fig. 1, 3-5, the guard 2 is fitted with a width light 4. The guiding is provided during the passing of the personnel and the vehicles, so that the safety of the personnel and the vehicles is ensured, especially under the condition that the ultra-wide vehicles pass and all the protection devices 2 on the two sides are turned over and opened. Preferably, the width lamp 4 is a solar warning lamp.

When the trestle is overlong, the driving device 3 can not smoothly drive the whole protecting device 2 to turn over, the protecting device can be split into multiple sections, and each section is provided with the driving device 3. When in use, each driving device 3 synchronously acts to drive each section of protection device 2 to turn over.

The working process and principle of the utility model are as follows:

during installation, rail guard 21 fixed mounting is on rotating the back shaft 22, rotates back shaft 22 through bearing frame 23 pivoted and installs on the crossbeam 12 of landing stage 1, and drive arrangement 3 installs on the longeron 11 of landing stage 1, and drive arrangement 3 rotates, drives first sprocket 31 and rotates to drive second sprocket 33 through chain 32, thereby drive and rotate back shaft 22 and rotate, thereby drive rail guard 21 upset, simple structure is convenient for production and preparation, and can be convenient install on the landing stage now additional.

When a person passes, the guards 2 on both sides of the two channels 13 are all turned up, see fig. 3, which is a state that is commonly used for working hours.

When the vehicle is not passing by the super width, see fig. 4, the guard 2 inside the two channels 13 is turned over and falls down.

When the ultra-wide vehicle passes through, see fig. 5, at this time, the protection devices 2 on both sides of the two channels 13 are all turned over and fall down, and the width indicating lamp 4 provides line guidance.
