[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model embodiment discloses a bridge and tunnel engineering construction isolation device.

[0026] The utility model provides Figure 1-3 The illustrated bridge and tunnel construction isolation device comprises a column 1 and a plurality of symmetrically arranged universal wheels 2 fixed at the bottom of the column 1. A rotating rod 3 is rotatably penetrated at the inner middle end of the column 1. A plurality of isolation sleeves 4 which are sequentially sleeved are fixed at one end of the rotating rod 3. Reflective warning strips 11 are fixed at the bottom of the tube wall of the plurality of isolation sleeves 4. Sliding holes 5 are opened in the tube walls of the plurality of isolation sleeves 4. Sliding rods 6 are slidably penetrated in the plurality of sliding holes 5. The sliding rods 6 are fixedly connected to the isolation sleeves 4. Two symmetrically arranged lighting indicator lights 16 are fixed at the upper end of the outer wall of the column 1.

[0027] Before the construction of bridges and tunnels, the device is moved to the position to be isolated by the universal wheel 2, and then the rotating rod 3 is rotated to rotate the multi-section isolation sleeve 4 to a horizontal position, and then the two adjacent isolation sleeves 4 are adjusted in turn, so that the overall length of the multi-section isolation sleeve 4 can be adjusted according to the isolation range to ensure the isolation effect. At the same time, with the setting of the reflective warning strip 11, a good isolation warning can also be given at night. At the same time, the setting of the lighting indicator light 16 can illuminate the construction area within a certain range during the construction of bridges and tunnels, which is convenient for adjusting the device.

[0028] In order to be able to quickly adjust the distance between two adjacent isolation sleeves 4, Figure 1 and Figure 3 As shown, an adjustment and positioning mechanism is provided between the slide rod 6 and the isolation sleeve 4, and the adjustment and positioning mechanism includes a fixed rod 7, the fixed rod 7 is fixedly connected to the end of the slide rod 6, and the rod wall sliding sleeve is provided with a plug plate 8, the tube wall of the isolation sleeve 4 is provided with a plurality of positioning grooves 9 arranged at intervals, and the end of the plug plate 8 away from the fixed rod 7 is inserted into the positioning groove 9, and the rod wall sleeve of the fixed rod 7 is provided with a spring 10, and the two ends of the spring 10 are respectively fixedly connected to the fixed rod 7 and the plug plate 8, and the plug plate 8 is arranged in an L shape.

[0029] When it is necessary to adjust the length between the isolation sleeves 4, first pull the plug plate 8 on the outside of the two adjacent isolation sleeves 4, so that the plug plate 8 slides along the fixing rod 7 and squeezes the spring 10, so that the plug plate 8 is separated from the positioning groove 9, and then the distance between the two adjacent isolation sleeves 4 can be adjusted under the sliding cooperation of the sliding rod 6 and the sliding hole 5, and the plug plate 8 is released after the adjustment is completed, and the elastic force of the spring 10 is restored to make the plug plate 8 inserted into the positioning groove 9, and the position of the sliding rod 6 is fixed, thereby completing the distance adjustment between the isolation sleeves 4.

[0030] In order to quickly store the multiple isolation sleeves 4 after the isolation work is completed, Figure 1-2 As shown, a rotating storage mechanism is provided at the other end of the rotating rod 3, and the rotating storage mechanism includes a worm wheel 12 and a worm 13. The worm wheel 12 is fixedly sleeved on the rear end of the rotating rod 3 and meshed with the worm 13. Two fixing plates 14 are fixedly provided on the back side of the column 1. The worm 13 is rotatably provided between the two fixing plates 14. The bottom of the worm 13 passes through the fixing plate 14 and is fixedly provided with a crank 15.

[0031] With the sliding cooperation between the slide rod 6 and the slide hole 5, the multi-section isolation sleeve 4 can be quickly retracted and enter the middle isolation sleeve 4, and then the crank 15 can be turned to rotate the worm 13. Through the engagement of the worm 13 and the worm wheel 12, the worm wheel 12 can drive the rotating rod 3 to rotate, so that the multi-section isolation sleeve 4 can be rotated to a vertical position, thereby reducing the space occupied by the device and facilitating the rapid movement and transportation of the device.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
