Description

Technical Field

[0001] The utility model relates to the technical field of track construction, in particular to a card-controlled tool for installing a roadbed template of an urban track. Background Art

[0002] Currently, the construction control of formwork erection is mainly carried out manually. First, the edge of the formwork is controlled by manual tape measurement. After the formwork is erected, the tape measure is used to measure the exact value from the edge of the formwork to the edge of the rail or sleeper. During the formwork erection, each formwork is measured three times to ensure the formwork's direction requirements. Then, the formwork height is controlled. A 2000m long square tube is placed on the rail surface to measure the formwork height. According to the design, the formwork height is 400mm below the rail surface. After the erection is completed, the square tube is used for review to check the overall linearity of the completed formwork. All of this is done manually. The main problems are as follows: First, because the direction of the formwork is controlled by the staff using a tape measure, human operation errors are prone to occur. Second, the formwork height is set based on the return of the rail surface on one side, which makes it impossible to achieve it in curved sections. Third, after the formwork is erected, the acceptance personnel need to organize the acceptance work again, which prolongs the construction period. Utility Model Content

The first clamping rod 5 is perpendicular to the horizontal connecting rod 3 and is connected to the horizontal connecting rod 3 The bottom is connected to form a ┬-shaped structure for easy clamping of the rail 8. The horizontal adjuster 6 is located at the top of the horizontal connecting rod 3, and the level ruler 7 is installed at the end of the horizontal connecting rod 3 away from the adjusting connecting rod 4; the positioning member 2 includes a vertical rod 9 and a second clamping rod 10. The top of the vertical rod 9 along the length direction is connected to the bottom of the horizontal connecting rod 3. There is a distance between the vertical rod 9 and the first clamping rod 5. The second clamping rod 10 is perpendicular to the vertical rod 9. The second clamping rod 10 is connected to the vertical rod 9 to form a ┤-shaped structure for easy restriction of the position of the semicircular ditch template 11.

[0030] When the horizontal link 3 is not horizontal, the horizontal link 3 is kept horizontal by the level adjuster 6, and the angle of the horizontal link 3 is checked by the level ruler 7. When the horizontal link 3 is not horizontal, the direction of the horizontal link 3 is adjusted by the level adjuster 6 until the level ruler 7 shows that the horizontal link 3 is in a horizontal state, and the adjustment is stopped. At this time, the horizontal link 3 is clamped to the working surface of the rail 8 and is in a horizontal state. The vertical rod 9 is vertically downward, and the second clamping rod 10 extends horizontally outward along the vertical rod 9. The height adjustment screw of the template bracket 16 is adjusted so that the top of the semicircular ditch template 11 contacts the bottom of the second clamping rod 10, and the side wall of the semicircular ditch template 11 contacts the vertical rod 9, that is, the position of the semicircular ditch template 11 is limited by the second clamping rod 10 and the vertical rod 9.

[0031] The horizontal adjuster 6 includes an adjusting screw 13 and a connecting block 17. The adjusting screw 13 is threadedly connected to the connecting block 17. The connecting block 17 is located on the horizontal connecting rod 3 and the adjusting connecting rod 4. The connecting block 17 is fixedly connected to the adjusting connecting rod 4. A threaded hole 14 is provided on the connecting block 17. The threaded hole 14 is located on the upper side of the horizontal connecting rod 3. After the adjusting screw 13 passes downward through the threaded hole 14, it is tightened against the horizontal connecting rod 3 to adjust the angle of the horizontal connecting rod 3.

[0032] In this embodiment, the adjusting screw 13 is a T-shaped screw, and the connecting block 17 is an inverted L-shaped structure. The height of the adjusting screw 13 is greater than the height of the connecting block 17. The vertical end of the connecting block 17 is fixedly connected to the adjusting link 4 away from the lateral end. The lateral end of the connecting block 17 is located on the upper side of the horizontal link 3, and the lateral end of the connecting block 17 is provided with a threaded hole 14. The threaded hole 14 is located on the upper part of the horizontal link 3. The external thread of the adjusting screw 13 matches the internal thread of the threaded hole 14. After the end of the adjusting screw 13 is screwed downward into the threaded hole 14, it passes through the threaded hole 14 to apply a downward force to the horizontal link 3, or the adjusting screw 13 is screwed upward along the threaded hole 14 to reduce the downward pressure of the adjusting screw 13 on the horizontal link 3, then the horizontal link 3 is adjusted upward or downward along the bearing 12.

[0034] In this embodiment, the counterweight 15 can be detachably mounted on the adjusting link 4. When the horizontal link 3 and the first clamping rod 5 are both in close contact with the working surface of the rail 8, the position of the counterweight 15 on the adjusting link 4 is adjusted so that the horizontal link 3 and the first clamping rod 5 remain clamped with the rail 8, and the horizontal link 3 remains horizontal.

[0035] In another possible embodiment, both ends of the adjusting link 4 along the length direction are connected to horizontal links 3, and each horizontal link 3 is connected to a first clamping rod 5, a horizontal adjuster 6, a level ruler 7 and a positioning member 2. The horizontal links 3 at both ends of the adjusting link 4 are adjusted horizontally at the same time, and the position of the semicircular ditch template 11 on both sides of the track is limited by the positioning member 1, which can improve the installation efficiency of the semicircular ditch template 11.

[0036] The horizontal connecting rod 3 is a rectangular rod made of metal material, and the level ruler 7 is magnetically attracted to the top of the horizontal connecting rod 3.

[0037] In this embodiment, the level 7 is magnetically attracted to the end of the horizontal connecting rod 3 away from the adjustment connecting rod 4 through a magnetic sheet. After use, the level 7 can be stored in a tool box to extend the service life of the level 7.

The distance between the bearing 12 and the end of the adjusting connecting rod 4 is 50 mm. The bearing 12 is located on the side of the horizontal adjuster 6 close to the rail 8.

[0040] In this embodiment, after the bearing 12 is passed horizontally through the horizontal connecting rod 3 and the adjusting connecting rod 4, a rotational connection is formed between the horizontal connecting rod 3 and the adjusting connecting rod 4.

The position of the second clamping rod 10 on the vertical rod 9 is adjusted, and the second clamping rod 10 is locked after the second clamping rod 10 is moved to the target position, thereby improving the applicability of the clamping tooling.

[0043] When in use, the bearing 12 is passed horizontally through the horizontal connecting rod 3 and the adjusting connecting rod 4, so that the horizontal connecting rod 3 and the adjusting connecting rod 4 are rotatably connected, and the first clamping rod 5 is pressed against the inner wall of the rail head of the rail 8. At this time, the bottom of the horizontal connecting rod 3 is pressed against the top of the rail 8, and then the angle between the horizontal connecting rod 3 and the top of the rail 8 is adjusted by the horizontal adjuster 6. When the pointer of the level ruler 7 returns to zero, the horizontal connecting rod 3 is in a horizontal state. Since the vertical rod 9 is vertical to the bottom of the horizontal connecting rod 3, the positions of the vertical rod 9 and the second clamping rod 10 are fixed, and the position of the semicircular ditch template 11 is erected by the template bracket 16. The bolts are used to pass through the template bracket 16 to adjust the template height so that the top of the semicircular ditch template 11 is pressed against the second clamping rod 10, and the side wall of the semicircular ditch template 11 is pressed against the vertical rod 9. The height and direction of the semicircular ditch template 11 are limited by the second clamping rod 10 and the vertical rod 9, so that the installation height of the semicircular ditch template 11 is consistent. This device has changed the previous cumbersome positioning and measurement method, improved construction efficiency and saved manpower.

[0044] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent structural transformation made to the above embodiment based on the technical essence of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
