Description

Technical Field

[0001] The invention relates to the field of road construction, and more specifically to a hot rod type highway roadbed widening device for ice-rich and ice-saturated road sections. Background Art

[0002] When carrying out roadbed widening work in frozen soil areas such as those rich in ice or saturated in ice, the underground ice below the surface in the frozen soil area has rheological properties. Therefore, when carrying out roadbed widening construction in this area, considering the frost heave and thaw settlement of the underground ice, it is necessary to drill holes on both sides of the roadbed to install hot rods. Hot rods are divided into inclined installation and vertical installation. Therefore, before drilling holes on both sides of the roadbed, the drill rod of the drilling rig needs to be adjusted and limited in azimuth. However, the surface flatness on both sides of the roadbed is not fixed, and the current equipment for adjusting the azimuth of the drill rod is simple in structure, which makes the drill rod not stable enough when drilling oblique holes, resulting in the oblique hole opening angle not being standard. In view of this, we propose a hot rod type highway roadbed widening device for ice-rich and saturated ice sections. Summary of the invention

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] 1. The present invention drives the connecting plate connected to the rotating rod to move by rotating the push rod, and the connecting plate drives the slide plate to slide to the left in the base. The oblique hole cooperates with the limit hole to drive the slide bar to move, so that the roller rises while the connecting rod descends, and then the fixed cone extends out of the base and is stably connected to the ground. The drill rod is limited by the limit cylinder and the rotating seat B, so that the drill rod can drill stably and accurately, improve the construction accuracy, and has good practicality.

[0018] 2. When the present invention drives the skateboard to slide left and right by rotating the push rod, the fixed cone and the roller move in opposite directions in the vertical direction, so that the present invention can easily and quickly switch between stable connection with the ground and pushing movement, which is beneficial to improving work efficiency.

[0019] 3. When the roller of the present invention contacts the ground, the push rod is in an inclined state, which is convenient for holding the push rod to push the present invention. When the fixed cone contacts the ground, the push rod rotates to fit the base, thereby reducing the occupied space and facilitating drilling with the drill rod.

[0031] A hot rod type highway roadbed widening device for ice-rich and ice-saturated road sections comprises a base 1, connecting rods 2 are slidably connected in both sides of the base 1, a plurality of fixed cones 3 are fixedly connected to the bottom surface of the connecting rod 2, a slide plate 4 slidably connected to the base 1 is provided on one side of the connecting rod 2, a plurality of oblique holes 401 are opened on the slide plate 4, a slide bar 5 is slidably connected in the oblique hole 401, the slide bar 5 located in the upper part of the oblique hole 401 is fixedly connected to the connecting rod 2, and the remaining slide bars 5 pass through the base 1 and are rotatably connected to rollers 6.

[0032] The base 1 is connected with a pushing mechanism 7 which can push the slide plate 4 to move. The base 1 is fixedly connected with a limit cylinder 12 on the upper side. The limit cylinder 12 is rotatably connected with a rotating seat B14 on both sides through a rotating shaft 13. The rotating seat B14 is fixedly connected with the base 1.

[0033] In the present technical solution, the pushing mechanism 7 can drive the slide plate 4 to slide in the left and right directions in the base 1. When the slide plate 4 slides, the slide bar 5 in the oblique hole 401 cooperates with the base 1 to move up and down, so that the roller 6 and the connecting rod 2 respectively connected to the slide bar 5 simultaneously perform opposite movements in the vertical direction, that is, when the roller 6 descends, the connecting rod 2 drives the fixed cone 3 to retract into the base. At this time, the roller 6 contacts the ground to facilitate driving the present invention to move. When the roller 6 rises, the connecting rod 2 drives the fixed cone 3 to descend to the lower side of the base 1. After the fixed cone 3 is plugged into the ground, the present invention is stably connected to the ground. The base 1 cooperates with the limit cylinder 12 through the rotating seat B14. The limit cylinder 12 can be adjusted to the required angle, so that the drill rod passes through the limit cylinder 12 for stable and accurate drilling.

[0034] Specifically, two adjacent oblique holes 401 are arranged in a V-shape.

[0035] In this technical solution, the sliding rods 5 in the adjacent oblique holes 401 are connected to the connecting rods 2 and the rollers 6 respectively.

[0036] Furthermore, the slide rod 5 is slidably matched with the limiting hole 101 provided on the base 1 .

[0037] In this technical solution, the oblique hole 401 cooperates with the limiting hole 101 to enable the slide bar 5 to move in the vertical direction.

[0038] Furthermore, the pushing mechanism 7 includes two rotating seats A701 fixedly connected to the base 1, a push rod 702 with a U-shaped structure is rotatably connected between the two rotating seats A701, a rotating rod 703 is fixedly connected to the lower part of the push rod 702, and the rotating rod 703 is slidably matched with the connecting plate 8 fixedly connected to the skateboard 4.

[0039] In this technical solution, the push rod 702 drives the rotating rod 703 to rotate, and the rotating rod 703 drives the sliding plate 4 connected to the connecting plate 8 to slide left and right.

[0040] Furthermore, a limiting rod 9 with a U-shaped structure is slidably connected to the push rod 702, and a plurality of limiting grooves 704 are provided on the rotating seat A701, and the limiting rod 9 is plugged into and matched with the limiting grooves 704.

[0041] In this technical solution, see Figure 4 When the limiting rod 9 is plugged into the limiting groove 704 on the left, the push rod 702 fits against the top surface of the base 1, reducing the occupied space and facilitating the drilling work of the drill rod. When the limiting rod 9 is plugged into the limiting groove 704 on the right, the push rod 702 is tilted, and the push rod 702 is held to drive the present invention to move.

[0042] Furthermore, springs 10 are sleeved on both sides of the lower part of the limiting rod 9, and the two ends of the spring 10 are respectively connected to the limiting rod 9 and the push rod 702.

[0043] In this technical solution, the spring 10 enables the limiting rod 9 to be stably plugged into the limiting groove 704 without being pulled by human power.

[0044] Furthermore, bolts 15 are threadedly connected on both sides of the limit tube 12, and the lower end of the bolt 15 is rotatably connected to the limit block 16. The limit block 16 is provided with a slot 1601, and a fan gear 17 is fixedly connected to the rotating seat B14, and the slot 1601 is engaged with the fan gear 17.

[0045] In this technical solution, when the slot 1601 is engaged with the sector gear 17 at different positions, the limiting cylinder 12 can be driven to adjust to different angles.

[0046] Furthermore, the limit block 16 is in sliding contact with the limit cylinder 12, and the limit block 16 is in sliding contact with the rotating seat B14.

[0047] In this technical solution, the limit block 16 moves up and down while keeping its own angle unchanged.

[0048] Furthermore, a pointer 18 is fixedly connected to the end of the rotating shaft 13 , an angle measuring plate 19 is rotatably connected to the rotating shaft 13 , and a counterweight 11 is fixedly connected to the bottom surface of the angle measuring plate 19 .

[0049] In this technical solution, the counterweight 11 drives the angle measuring plate 19 to always maintain a vertical state, and the pointer 18 cooperates with the angle measuring plate 19 to drive the limiting cylinder 12 to adjust to accurate parameters.

When the push rod 702 rotates, it drives the slide plate 4 connected to the connecting plate 8 to slide to the left. At this time, the slide rods 5 of the multiple oblique holes 401 respectively rise or fall, so that the roller 6 rises, and the connecting rod 2 drives the fixed cone 3 to descend to the lower side of the base 1.
